Fix reloadSession race that orphans streamingMsg ...

reloadSession checked streaming.value at entry but api.getSession is
async. While awaiting, onStreamStart could set streaming=true and push
the assistant message into messages.value. When reloadSession resumed it
replaced messages.value with the stale server snapshot, evicting the live
streaming message. All subsequent deltas and tool cards went to the orphan
and were invisible.

Fix: re-check streaming.value after the await before mutating messages.

Fix delta loss during thinking-to-text transition and streaming orphaning ...

Backend:
- agent.py _consume_stream: replace elif with if so a single chunk can
  carry both the final thinking fragment AND the first text delta.
  Fixes the 'first token lost after tools' bug.

Frontend:
- chat.js reloadSession: bail out early when streaming.value is true.
  Replacing messages.value mid-stream orphans streamingMsg, breaking
  Vue reactivity for all subsequent deltas and tool cards.
- useWebSocket.js session_sync handler: add !chat.streaming guard
  before calling reloadSession.

Fix streaming message orphaning and duplicate message keys ...

chat.js:
- reloadSession: during an active stream, replace the last built assistant
  message with the live streamingMsg instead of discarding it on text match.
  This fixes the root cause of invisible first messages and flickering tool
  cards when session_sync arrives mid-stream.
- buildMessageList: remove assistantCounter and use firstIdx as the message id
  to avoid duplicate Vue keys (e.g. user h_0 and assistant h_0).

Fix 19 issues found in full codebase review ...

Backend:
- Stop session auth bypass: require auth for owned sessions, reject anonymous with 401
- upload_file: stream chunks directly to disk instead of buffering in RAM
- MCP config: validate name against path traversal regex
- auth deps: cleanup stale refresh locks periodically
- auth routes: expire mobile auth states after 10 min to prevent unbounded growth
- compressor: meta-summarize existing summaries before compression; preserve assistant content when tool_calls present; rewrite hard_truncate to keep whole turns
- orchestrator: configurable WS replay buffer size; async cleanup/remove_websocket/clear_busy; fix run_recall ContextVar order to avoid deadlock on _build_agent failure; await cleanup in finally

Add client-side image resize and server-side image token budgeting ...

Client (useFileUpload.js):
- Resize images to max 1024px on longest side via Canvas before upload
- JPEG quality 0.9, preserves EXIF orientation
- Reduces typical phone photos from 8 MB → ~400-900 KB

Server (websocket.py):
- Increase limit to 8 images, 50 MB total payload

Server (agent.py):
- Before adding user message to session.context, estimate how many images
  fit in remaining context (500 tok/img, up to 80% of max_context_tokens)
- Images that don't fit are saved as resized JPEGs to session_files/
- References to saved images are appended to the user message text
  so Navi can view them later via image_view tool
- session.messages keeps ALL images for full UI history

Fix MCP tool spinner bug: match tool_started → tool_call by tool_call_id ...

- Add tool_call_id field to ToolStarted and ToolEvent dataclasses
- Pass tc.id as tool_call_id from agent.py, subagent_runner.py, and tool_executor.py
- Update frontend chat.js onToolStarted/onToolCall to match cards by toolCallId
  with fallback to name-matching for backward compatibility

Closes spinner issue where LLM short name ("search_docs") didn't match
resolved MCP name ("mcp__gnexus_book__search_docs").

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.

Add MCP health check loop, auto-reconnect, and system toast notifications ...

Backend:
- McpManager: keep all configured servers in the pool even if connect()
  fails at startup; health-check loop (30s) tries to reconnect dead servers
  and verifies live ones with list_tools()
- McpManager: set_on_server_connected callback re-registers tools when a
  dead server comes back online
- McpClient: add mark_disconnected() for silent drop detection
- McpStatusTool: skip list_tools() for disconnected servers
- Orchestrator: broadcast mcp_status_update to all WebSocket sessions
- New event type McpStatusUpdate with server_name, status, tool_count

Webclient:
- useWebSocket: handle mcp_status_update → toast.success/toast.error

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"

  8 to 12 chars for better visual identification; add security notes

  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

- 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

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.
