Replace the standalone SSE dot above UserMenu with a small badge
overlaid on the bottom-right of the user avatar. Only visible when
status is connecting (yellow) or disconnected (red) — invisible in the
normal connected state, removing constant visual noise.

Add a comment preview section below memo cards in list view, displaying
up to 3 comment snippets with a "View all" link. Removes the old comment
count icon from the memo header in favor of this richer inline display.
Comment preview is hidden in memo detail view.

- Reduce themes from 6 to 4: system, light, dark, paper
  - Remove midnight (too similar to dark) and whitewall (too similar to light)
  - Drop all unused tokens: chart-*, sidebar-primary, sidebar-border,
    sidebar-ring, shadow-2xs, tracking-normal, spacing
  - Remove redundant @theme inline blocks from dynamic theme files
    (Tailwind only processes them at compile time, not at runtime)
  - Move shared tokens (fonts, radius) to default.css only

- Polish dark mode color palette
  - Consistent cool-slate hue (h265) across all surfaces
  - Proper surface layering: sidebar(0.07) → bg(0.09) → card(0.13) →
    popover(0.17) → secondary(0.19) → muted(0.21) → accent(0.22)
  - Foreground softened to 0.82 (from 0.9) — comfortable off-white
  - Accent more chromatic than muted (0.012 vs 0.008) — hover feels interactive
  - Popover elevated above card (0.17 vs 0.13) — floating elements visible
  - Destructive more vivid (0.62/c0.20) — clearly red on dark surfaces
  - Input border (0.25) more distinct than layout border (0.21)
  - Sidebar foreground (0.68) dimmer than content foreground (0.82)

- Fix inline code background invisible in dark mode (#5674)
  - Muted was same lightness as card — increased to 0.21 for clear contrast

- Replace PAT-only auth with optional auth supporting both PAT and JWT
  via auth.Authenticator.Authenticate(); unauthenticated requests see
  only public memos, matching REST API visibility semantics
- Inline auth middleware into mcp.go following fileserver pattern;
  remove auth_middleware.go
- Introduce memoJSON response type that correctly serialises store.Memo
  (including Payload.Tags and Payload.Property) without proto marshalling
- Add tools: list_memo_comments, create_memo_comment, list_tags
- Extend list_memos with state (NORMAL/ARCHIVED), order_by_pinned, and
  page parameters
- Extend update_memo with pinned and state parameters
- Extract #tags from content on create/update via regex to pre-populate
  Payload.Tags without requiring a full markdown service rebuild
- Add MCP Resources: memo://memos/{uid} template returns memo as
  Markdown with YAML frontmatter, allowing clients to read memos by URI
- Add MCP Prompts: capture (save a thought) and review (search + summarise)

Add migration scripts for existing instances without a storage setting
to explicitly preserve DATABASE as their storage type, ensuring backward
compatibility. Change the default for new installations to LOCAL to
improve out-of-the-box performance.

Align header padding, text color, background tokens, and item row styles
across CodeBlock, AttachmentList, RelationList, and LocationDisplay so all
metadata panels follow the same visual pattern.

- Add PR stale/close handling alongside issues
- Reduce close grace period from 7 to 3 days
- Add inline comments explaining the two-phase stale behavior
- Rename workflow and job names for clarity

When multiple tabs are open and a token expires, each tab independently
attempts a refresh. With server-side token rotation this causes all but
the first tab to fail, logging the user out.

Add a BroadcastChannel (memos_token_sync) so that when any tab
successfully refreshes, it broadcasts the new token to all other tabs.
Receiving tabs adopt the token in-memory immediately, skipping their own
refresh request and avoiding conflicts with token rotation.

Falls back gracefully when BroadcastChannel is unavailable (e.g. some
privacy modes).

Add ApplyToContext and AuthenticateToUser helpers to the auth package,
then remove the duplicated auth code spread across the MCP middleware,
file server, Connect interceptor, and gRPC-Gateway middleware.

- auth.ApplyToContext: single place to set claims/user into context after Authenticate()
- auth.AuthenticateToUser: resolves any credential (bearer token or refresh cookie) to a *store.User
- MCP middleware: replaced manual PAT DB lookup + expiry check with Authenticator.AuthenticateByPAT
- File server: replaced authenticateByBearerToken/authenticateByRefreshToken with AuthenticateToUser
- Connect interceptor + Gateway middleware: replaced duplicated context-setting block with ApplyToContext
- MCPService now accepts secret to construct its own Authenticator

Embeds a Model Context Protocol (MCP) server into the Memos HTTP
process, exposing memo operations as MCP tools at POST/GET /mcp using
Streamable HTTP transport.

Authentication is PAT-only — requests without a valid personal access
token receive HTTP 401. Six tools are exposed: list_memos, get_memo,
create_memo, update_memo, delete_memo, and search_memos, all scoped to the authenticated user.

Two bugs caused users to be redirected to /auth too frequently:

1. Race condition in Promise.all([initInstance(), initAuth()]):
   initInstance() makes a gRPC request whose auth interceptor calls
   getAccessToken() synchronously. When the access token was expired,
   getAccessToken() eagerly deleted it from localStorage as a "cleanup"
   side-effect. By the time initAuth() ran and checked hasStoredToken(),
   localStorage was already empty, so it skipped the getCurrentUser()
   call and the token refresh cycle entirely — logging the user out even
   when the refresh-token cookie was still valid. Fix: remove the
   localStorage deletion from getAccessToken(); clearAccessToken()
   (called on confirmed auth failure and logout) handles proper cleanup.

2. React Query retry: 1 caused a second refresh+redirect attempt after
   auth failures. The auth interceptor already handles token refresh and
   request retry internally. If it still throws Unauthenticated, the
   redirect is already in flight — a React Query retry only fires another
   failed refresh and a redundant redirectOnAuthFailure() call. Fix: use
   a shouldRetry function that skips retries for Unauthenticated errors
   while keeping the existing once-retry behaviour for other errors.

The explore page sidebar was showing tags from the current user's private
memos because the default ListMemos query applies a server-side OR filter
(creator_id == X || visibility in [...]), mixing private content in.

Fix by using a visibility-scoped ListMemos request in the explore context
so private memos are always excluded via the AND'd server auth filter.

Also consolidate two always-firing useMemos calls into one context-aware
query, unify activity stats computation with countBy across all branches,
and extract a toDateString helper to remove duplicated formatting logic.

Use useTranslation() hook instead of the static i18n import so that
the month label re-computes when the language changes.
