Fix terminal detail UX: description wrapping, status contrast, close button ...

- Remove `white-space: nowrap` from `.terminal-detail-meta` and
  `.terminal-item .artifact-meta` — long descriptions now wrap instead
  of being clipped with ellipsis.
- Add `-webkit-line-clamp: 2` to list-item meta so description is
  limited to 2 lines with graceful overflow.
- Fix status colour in detail rows: `.terminal-detail-value.status-busy`
  etc. added after `.terminal-detail-value` so their colours override
  the default #C0CAF5 (was causing light-on-light text).
- Add close button (X) inside `.terminal-detail-header` to dismiss
  the detail pane without leaving the tab.
- Make `selectTerminal` toggle: second click on the same item deselects.
- Build webclient and run tests — all pass.

Fix link deduplication in ArtifactsPanel — three root causes ...

1. normalizeUrlForDedup returned only pathname, so https://a.com/foo
   and https://b.com/foo shared key /foo. Now uses host+pathname
   (with www stripped).
2. Trailing punctuation was stripped for display but not before dedup,
   so https://example.com/path. and https://example.com/path got
   different keys /path. vs /path. Now stripTrailingPunctuation() runs
   before normalizeUrlForDedup().
3. Fragile before==='(' skip logic for markdown hrefs replaced with
   precise protectedRanges tracking — bare URLs whose match falls inside
   a recorded markdown href range are skipped regardless of spacing.

Show copied checkmark on token copy button for 1.5s ...

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

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
- webclient/src/composables/useWebSocket.js: add security comment about
  localStorage XSS risk and query param log exposure

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.

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)

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)

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)

- 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)

- In-memory store: search_list also filters by message content

Frontend:
- AppSidebar: search toggle icon + debounced input, Ctrl+K shortcut
- SessionItem: highlight matching text, show match_preview from search
- SessionList: pass searchQuery to SessionItem
- SessionsStore: searchQuery/searchActive state, setSearch/clearSearch
- API layer: getSessions accepts search param
- MessageList: scroll to target message + brightness flash animation
- ChatStore: loadSession accepts targetMessageIndex, scrollToMessageIndex ref
- CSS: msg-flash keyframe animation in app.scss
- Tests updated for new getSessions signature

- ToolCard: remove emoji header, collapse Arguments behind <details>,
  render results with structured JSON (color-coded values) or markdown
  detection for string outputs.
- SubagentStep: mirror ToolCard compact layout with same helpers.
- AssistantMessage: fold tool lists when >3 tools — show last 3 + summary
  bar with count and toggle icon-button; TransitionGroup for smooth
  expand/collapse animations.
- Plan card: switch accent color from info to secondary, compact sizing.
- Thinking card: compact sizing, remove bottom margin.
- app.scss: add details::details-content animation, fix nested chevron

Markdown images: adaptive 3-column grid, lightbox modal, and broken-image handling ...

- useMarkdown.js: custom marked renderer wraps images in clickable links with
  inline onerror for broken-image detection
- app.scss: .msg-assistant-content becomes flex-wrap container; image paragraphs
  sized to 3-per-row via calc((100% - 16px) / 3); images are square via
  aspect-ratio: 1 / 1 and object-fit: cover
- ImageLightbox.vue: rewritten with proper gnexus-ui-kit .modal/.modal-dialog
  DOM structure; broken images show error placeholder inside modal
- AssistantMessage.vue: attachImageLightbox() wired after v-html render
- Broken images: .is-broken class prevents lightbox click; CSS shows 🖼️ icon

Persist uploaded files in messages, live file tree updates, and UI polish ...

Backend:
- Add `files` field to `Message` model so uploaded file metadata survives page refresh
- Pass `files` through websocket handler → `agent.run_stream` / `agent.run`
- `list_tools`: make `profile_id` required; return error instead of all-tools fallback

Webclient:
- Call `fetchFiles()` after successful file upload for immediate Files tab update
- Live refresh file tree on filesystem (write/edit/append/mkdir/rm/cp/mv), terminal, and code_exec tool calls
- Add manual refresh button (desktop) and pull-to-refresh (mobile) to Files tab
- Fix live link updates: move regex creation inside per-message loop to avoid lastIndex state leak
- Restore full profile name text next to avatar in ChatHeader; hide avatar in header
- Fix mobile ArtifactsPanel: collapse tab text labels so close button fits with 3 tabs
