* fix(oauth): stop treating a foreign window.opener as a bind flow

The /oauth/:provider callback decided between an account bind and a plain
login with `window.opener ? 'bind' : 'login'`. Any tab opened from an
external link (target="_blank", Slack, mail clients, another site) carries
a live opener, and that opener survives the cross-origin round trip to the
identity provider. Such a login callback was therefore misread as a bind:
it posted a handshake to a window that speaks no such protocol, showed the
"binding your account" screen, and hung until the 30s deadline fired with
"OAuth binding timed out" — while the backend was never called at all.

Reproduced against a real Keycloak round trip: a tab opened via window.open
still reports window.opener !== null on the callback, so mode resolved to
'bind' for an ordinary OIDC login.

A bind now requires positive proof: the popup we open for it is same-origin
(about:blank) before being sent to the provider, so we stamp its own
sessionStorage. The stamp rides through the provider round trip and is
scoped to that popup alone, so a login tab can never carry it. Ambiguity
resolves to 'login', which is the recoverable direction.

Affects every provider sharing this callback (OIDC, GitHub, Discord,
LinuxDO, custom).

* fix(oauth): harden bind popup detection

* fix: preserve qwen thinking budget

* test: address qwen thinking budget review comments

* chore: remove unreachable adaptor code

* test: cover zero Qwen thinking budgets

* docs: add design spec for OIDC custom display name

Mirrors the existing Custom OAuth Provider name pattern so admins can
show a meaningful label instead of the hardcoded "OIDC" on the login
page and in related copy.

* feat(oidc): add configurable display name with OIDC fallback

* feat(oidc): use configured display name in provider name and status API

* feat(oidc): add display name field to default-theme OIDC settings

Claude-Session: https://claude.ai/code/session_01FDkWJqigJi9yE3HG5pjZP5

* feat(oidc): show configured display name on default-theme login button

* feat(oidc): add display name field to classic-theme OIDC settings

* feat(oidc): show configured display name on classic-theme login button

* fix(oidc): trim whitespace before applying display name fallback

* chore: remove internal design doc from PR

Design/planning docs are working artifacts for this session and
shouldn't be submitted to the upstream project.

* fix(oidc): lead with example in classic-theme display name placeholder

Reorders the combined placeholder to show the example first, then
the fallback note, matching the Custom OAuth Provider Name field's
placeholder convention (example-only) that this feature mirrors.

* fix(i18n): improve Russian grammar in OIDC display-name placeholder translation

Leads each clause with its condition/subject and adds the missing
verb, per PR review feedback.

* test(web): remove redundant OIDC harness tests

* fix: parameterize slow/error SQL logs to avoid leaking credentials

* fix: validate SQL_SLOW_THRESHOLD_MS range

* fix: sanitize database driver error messages in SQL logs

* refactor: sanitize at gorm log writer seam to keep caller attribution

* test(relayconvert): add golden snapshot matrix and relaykit boundary guard

Phase 0 of the relaykit extraction plan: pin byte-level output of every
registered (from,to) request/response/stream conversion route, and
forbid kit-bound packages from growing host-only imports.

* wip(relayconvert): drop gin.Context from converter signatures; add convmeta draft

Phase 1 in progress: relayconvert now takes context.Context; host media
resolver adapts gin.Context back at the service boundary.

* refactor(relayconvert): decouple converters from RelayInfo, gin, and settings

Phase 1 of the relaykit extraction plan:
- converters now depend on convmeta.Meta (implemented by RelayInfo) instead
  of *relaycommon.RelayInfo; ClaudeConvertInfo and the format guesser move
  to convmeta with aliases left behind
- host settings reach converters via a convmeta.Options snapshot built in
  RelayInfo.ConvOptions; no more model_setting/reasoning global reads inside
  the conversion layer
- effort-suffix helpers move to service/relayconvert/reasoning (old package
  forwards); chat-to-responses upgrade policy moves to service (host routing
  logic, not conversion)
- golden conversion matrix unchanged

* test(relayconvert): tighten boundary — kit packages now free of gin/setting imports

* refactor(dto): drop gin and logger dependencies

Phase 2 (part 1): dto.Request.IsStream now takes *http.Request instead of
*gin.Context (Gemini's impl reads query/path off the std request); dto's
three logger calls become common.SysError. Boundary test allowlist is now
empty — kit-bound packages import no gin/setting/logger/model.

* refactor(kit): extract dependency-free kitutil; dto/types/relayconvert stop importing common

Phase 2 of the relaykit extraction plan:
- new service/relayconvert/kitutil holds the pure helpers the kit needs
  (JSON wrappers, pointer/string/uuid/timestamp utils, MaskSensitiveInfo,
  pluggable LogInfo/LogError hooks, Debug flag)
- dto, types, and all relayconvert packages now use kitutil; their only
  remaining internal deps are dto/types/constant
- common keeps every original symbol (MaskSensitiveInfo delegates to
  kitutil) so host code is untouched; main.go routes kit logging into
  common.SysLog/SysError and mirrors DebugEnabled
- golden conversion matrix unchanged

* refactor(kit): move EndpointType/FinishReason to types; OpenRouter dialect via Options

Kit packages (dto/types/relayconvert/reasonmap) no longer import constant:
- EndpointType and finish-reason values live in types; constant re-exports
- the OpenRouter special-case in claude->openai request conversion reads
  Options.OpenRouterDialect, set by the host from the channel type;
  InitChannelMeta invalidates the cached snapshot on channel switch

* refactor: extract relaykit submodule (dto/types/relayconvert/reasonmap)

Phase 3 of the relaykit extraction plan:
- new go module github.com/QuantumNous/new-api/relaykit containing dto
  (minus task family), types, relayconvert (with convmeta/kitutil/reasoning),
  and reasonmap; host consumes it via require + replace, go.work for dev
- task-family dto (task/suno/midjourney/video) stays in the host dto
  package; dual-consumer host files alias it as taskdto
- relaykit builds and tests standalone (GOWORK=off): no host imports,
  no gin, no DB, no settings
- golden conversion matrix unchanged

* build(docker): copy relaykit/go.mod before go mod download

The local-replace submodule's go.mod must exist inside the build context
for the main module graph to resolve.

* fix: address relaykit extraction regressions

* fix: address relaykit review regressions

* docs: document Meta nil receiver contract

* fix(relaykit): fail OpenAI→Claude conversion without max_tokens; reject negative default_max_tokens

The Claude Messages API requires max_tokens (omitting it is a 400
"Field required"), but with a nil Options.Claude.DefaultMaxTokens hook
the converters silently emitted a request the upstream is guaranteed to
reject. Both OpenAI Chat and Responses → Claude conversions now return
sharedclaude.ErrMissingMaxTokens when no path (client value, default
hook, thinking-adapter floor) supplied one. Unreachable in the host,
which always configures the hook.

Host side, claude.default_max_tokens now rejects negative values at the
option API before persisting — they would wrap into huge unsigned values
during conversion. Zero stays allowed: the current API treats
max_tokens: 0 as cache pre-warming.

* fix: make Gemini safety settings read path race-free

close #6461

Add admin-configurable tool-call prices with cross-provider surcharge
settlement, Sub2API channel support, /v1/alpha/search relay, and usage-log
surcharge UI.

* feat: support tencent tokenhub api key via openai-compatible protocol

* fix: use tokenhub base url for tencent api key channels

* test: cover tencent key-format dispatch and add TokenHub key prompt locales

The line-number layer spans the full editor, so giving it an opaque
background and raised z-index covered the highlighted content. Reverts
the gutter background added in 88868002f; the horizontal-scroll
gutter overlap it targeted returns as a known cosmetic issue.

* perf(json-editor): improve JSON editing experience

- integrate Yace for syntax highlighting, history, indentation, auto-closing, and smart line breaks.
- add copy support, cursor location feedback, and synchronized content and line-number scrolling.
- extract JSON editor utilities and cover key interactions with unit tests.

* perf(system-settings): improve JSON configuration editing

- replace raw JSON textareas with the shared editor for highlighting, validation, copy, and formatting.
- preserve field-specific examples and make placeholders visible through the transparent editor layer.
- remove duplicate formatting controls while keeping existing form validation and save behavior.

* perf(json-editor): standardize JSON inputs across admin settings

- replace pure JSON textareas with the shared editor across system settings and channel workflows.
- preserve form focus, validation, placeholders, and visual or JSON editing modes.
- add happy-dom component coverage for form bindings, controlled updates, and formatting.

* fix(json-code-editor): address accessibility review findings

- Drop the unconditional aria-label that overrode every field's
  label-derived accessible name; add an optional ariaLabel prop and
  set it at call sites without an associated label
- Associate standalone Labels via htmlFor/id in channel-affinity views
- Hide the highlight mirror and line-number layers from the
  accessibility tree (aria-hidden)
- Give the line-number gutter an opaque background so horizontally
  scrolled code no longer slides under it
- Degrade to no scroll sync instead of destroying the editor when the
  line-number layer is not found

* fix(channel): debounce inline priority updates

* fix(channel): commit spinner edits only on Enter or focus leave

Blurring the inline edit input to the +/- buttons flushed the pending
priority update immediately, bypassing the container focus-containment
check and defeating the debounce. Commit now happens via the container
blur handler or explicitly on Enter. Add unit tests for the priority
update scheduler.

* fix(channel): preserve row identity when priority updates reorder channels
