Apply review fixes to API token auth system ...

Backend:
- navi/auth/deps.py: replace 3 DB round-trips with single JOIN query for
  token resolution; update last_used_at still separate (best-effort)
- navi/api/routes/api_tokens.py: replace asyncpg-specific "UPDATE 1"
  string check with RETURNING id fetchrow; increase token_prefix from
  8 to 12 chars for better visual identification; add security notes
- tests/unit/auth/test_api_tokens.py: update tests for JOIN query and
  RETURNING-based revoke

Frontend:
- webclient/src/components/settings/ShowTokenModal.vue: new modal that
  shows the plain token in a readonly field with copy button and
  explicit warning — replaces the transient toast notification
- webclient/src/components/settings/ApiKeysPanel.vue: use ShowTokenModal

Add API token auth system for headless/micro clients ...

Backend:
- navi/auth/_ddl.py: add api_tokens table with boot-time migration
- navi/auth/deps.py: _resolve_user now falls back to X-Api-Token header
  and ?api_token query param for WebSocket auth
- navi/auth/__init__.py: add ApiToken pydantic model
- navi/api/routes/api_tokens.py: CRUD endpoints (POST/GET/DELETE)
- navi/main.py: wire api_tokens router

Frontend:
- webclient/src/App.vue: add #settings hash routing
- webclient/src/components/settings/: SettingsView, ApiKeysPanel,
  CreateKeyModal with copy-to-clipboard flow
- webclient/src/api/index.js: token CRUD API functions
- webclient/src/stores/apiTokens.js: Pinia store
- webclient/src/components/sidebar/AppSidebar.vue: settings link
- webclient/src/composables/useWebSocket.js: append ?api_token= when
  localStorage token is present

Tests:
- tests/unit/auth/test_api_tokens.py: 10 unit tests covering token
  resolution (header + query param), revoke, missing/revoked tokens,
  orphan users, and CRUD endpoints

Fix link deduplication in ArtifactsPanel ...

Normalize URLs by pathname (lowercased, no query/hash, no trailing
slash) so the same file reached via different query params or
absolute/relative forms is counted once.

ArtifactsPanel: two-pass link extraction — markdown links win over bare URLs ...

Markdown links carry a title/caption, so they should always take priority
over bare URLs during deduplication.  Previously a bare URL from a newer
message could shadow an older markdown link.  Now markdown links are
scanned in a separate first pass, so they always win the dedup race.

ArtifactsPanel: strip trailing punctuation from URLs for dedup ...

Bare URLs sometimes pick up a trailing ) or . from surrounding markdown
(e.g. model writes a link inside parentheses). The normalizeUrlForDedup()
helper strips trailing punctuation before checking the seen Set so
https://a/b and https://a/b) are treated as the same link.

Add legacy redirect for session files and fix STL viewer error handling ...

- Add /sessions/{id}/files/{filename} → /api/sessions/{id}/files/{filename}
  redirect in main.py for backward compatibility with old persisted URLs
- Fix STL viewer: wrap all renderer-dependent code in `if (renderer)`
  to prevent cascading errors when WebGL is unavailable
- Rebuild dist

Fix SyntaxError: Illegal return statement in STL viewer ...

The previous fix replaced `throw err` with `return` inside a module,
but top-level `return` is a SyntaxError in ES modules.
Reverted to `throw err` — the error message is already shown on screen,
so the user still gets a graceful fallback even though the error appears
in the console.

Fix session file URLs (add /api prefix) and WebGL error handling in STL viewer ...

Backend:
- _file_url in content_store.py now returns /api/sessions/... instead of /sessions/...
- share_file.py URL construction updated to include /api
- content_publish.py docstring updated to reflect correct endpoint

Frontend:
- contentLinks.js: avoid double /api prefix in dev mode when backend already returns it
- stl.html: replace throw err with return after showing WebGL fallback message
- Rebuild dist

Tests:
- Update expected URLs in test_content_store.py and test_share_file.py

fix(webclient): add missing updatePreview and updateName in sessions store ...

updatePreview and updateName were referenced in the store's return object
but never defined, causing ReferenceError at runtime after build.

Refactor: move tool helper modules into _internal subpackage ...

Moves non-tool infrastructure out of navi/tools/ root so that only
actual tool classes live there:

  base.py           → _internal/base.py
  loader.py         → _internal/loader.py
  middleware.py     → _internal/middleware.py
  logging_middleware.py → _internal/logging_middleware.py
  _time_parser.py   → _internal/time_parser.py

All imports updated across core/, api/, mcp/, tools/, and tests/.
No proxy files remain in navi/tools/ root.

Fix search spinner overlay on magnifying-glass icon ...

- Replace opacity-based hiding with display:none on .input-group-addon > i.
  Move spinner pseudo-element to nested &::after inside .input-group-addon
  with display:block + margin:auto for reliable centering.
- Tests pass (51/51)

Fix search spinner overlay, scroller reset, highlight leak ...

- AppSidebar: use i.ph selector + !important for spinner overlay on
  input-group-addon icon. Add transition for smooth fade.
- SessionList: simplify DynamicScroller :key to 'search'/'all' only,
  removing sessions.length to prevent scroll reset on fetchMore.
- SessionList: pass empty searchQuery when searchActive is false,
  preventing stale highlights in normal session list.
- Tests pass (51/51)

Rebuild dist for final search UX polish ...

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Final search UX polish: focus, cache, spinner opacity, scroller key ...

- AppSidebar: auto-focus input when search opens via querySelector.
  Spinner icon now hides via opacity:0 instead of visibility:hidden.
- SessionsStore: add searchCache ref + restoreSearch(). Cache stores last
  search results (items, hasMore, nextOffset) so reopening search avoids
  re-fetching when query hasn't changed.
- SessionList: add :key on DynamicScroller to force recreate when switching
  between search/normal mode, fixes pinned item spacing bug.
- Tests pass (51/51)

Fix search spinner placement, msg-flash disappearance, results cleanup ...

- AppSidebar: spinner moved inside GnSearchField input-group-addon via CSS
  (:deep .input-group-addon overlay). Removed spinner from sessions-label.
- AppSidebar: closeSearch and handleSelect now call sessionsStore.exitSearch()
  and reload normal session list, so search results disappear after selection.
  toggleSearch restores previous query and re-activates search on reopen.
- CSS msg-flash: removed animation-fill-mode:both and background-color:transparent
  from keyframes, so message bubble keeps its original background after flash.
- SessionsStore: added exitSearch() method (preserves query, disables active flag).
- Tests pass (51/51)

Rebuild dist for search flash and highlight fixes ...

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Fix search flash for assistant messages, move spinner, hide highlights ...

- MessageList: pass isFlashing prop to UserMessage/AssistantMessage instead
  of applying msg-flash on wrapper div. scrollToMessage now uses rawIndices
  to map backend match_index to grouped message index.
- UserMessage: add isFlashing prop, apply msg-flash to msg-user-bubble
- AssistantMessage: add isFlashing prop, apply msg-flash to msg-assistant-content
- ChatStore: add rawIndices to built messages (user, summary, assistant)
- AppSidebar: move spinner into sessions-label, remove from search field
- SessionList: accept searchOpen prop, pass empty searchQuery when closed
  so highlights disappear after selecting a session
- Tests pass (51/51)

Polish session search UX: GnSearchField, spinner, flash timing ...

- AppSidebar: use GnSearchField from gnexus-ui-kit, spinner during search,
  search toggle button always visible in sessions-header, hide search on select
- MessageList: fix msg-flash timing — make content visible before scrolling,
  extend flash duration to 2.5s with background + brightness
- CSS: enhance msg-flash keyframe animation
- Tests pass (51/51)
