Post-merge follow-ups for #2740#2735#2734#2690#2676#2738#2684#2689#2733#2739#2462#2687#2736#2618#2697, plus three regressions
found while reviewing them:
- ctrl/cmd+digit while typing no longer switches session tabs (#2503 was
still open in practice: the guard only covered the mod+alt surface binding)
- Shiki template-call sanitizer now covers every bundled grammar, including
the js/ts aliases and embedding grammars; timed-out highlight requests are
memoized and no longer cancel unrelated in-flight requests
- settings flush on suspend uses keepalive and also fires on Capacitor
appStateChange; keeps the selected model persisted across mode switches
- remote-only branches fetch before checkout; range helpers fail clearly
- git status invalidation now fires for runtime adapters too
- settings number inputs and select triggers size in ch so they scale with
the interface font
- recent-activity timestamps tick from one list-level ticker
- Markdown preview find goes through the shared find_in_file keybind with
containment, no longer counts its own bar, and debounces observer runs
- #2676 reverted; #2524 fixed by fading the sticky header's own background
instead of overlaying the content below it
- sticky group headers in the model picker and sidebar render again
(oc-sticky-fade-scroller class restored after 9b9d7069c)
- project switcher names are left-aligned again (wrapper lost in 26dbc2f30)
- tool card quick-open icon is always visible and opens the same line as the
expanded card's button
- tautological tests replaced or removed; new oxlint findings fixed
Shiki's bundled JS/TS/JSX/TSX grammars carry a `template-call` rule whose
triple-nested lookahead sends the Oniguruma WASM engine into exponential
backtracking on ordinary backtick templates. The WASM heap grows until the
renderer runs out of memory and the window goes black.
Strip `template-call` from those four grammars as they are loaded in the
Shiki worker. Plain backticks and simple tagged templates still highlight;
only the rare `ident<TypeArgs>` tagged-template form loses its specialized
type-argument coloring.
Add a 5s per-request budget on the worker client as a safety net for any
other pathological pattern. Matching is synchronous inside the worker, so
the only way to reclaim its heap is to terminate it from the main thread.
A timed-out request resolves `null` like any other failure, so the caller
keeps plain text and nothing is written to the result cache.
Closes#2587
Neutralize the catastrophic TextMate template-call lookahead when loading
JS/TS grammars in the markdown Shiki worker, and terminate hung highlight
requests after 5s so unbounded Oniguruma WASM matching cannot OOM the
renderer (openchamber/openchamber#2587).

Improve OpenChamber responsiveness under large session workloads while fixing
cache, synchronization, and persistence correctness across runtimes, projects,
directories, and worktrees.
- prioritize selected and visible sessions during bootstrap and defer
non-critical enrichment work
- reduce redundant message loading, event processing, store publication, and
hidden sidebar work
- prevent stale session and message requests from overwriting newer
authoritative state
- preserve existing data when authoritative fetches fail instead of treating
failures as successful empty responses
- scope session materialization, messages, drafts, queues, todos, pins,
permissions, folders, tabs, Git state, and pull request data by runtime and
directory identity
- harden runtime switching, reconnect, cleanup, mutation reconciliation, and
persisted-state ordering
- preserve live subagent Task linkage when metadata arrives after an older
message request or while streaming parts are suspended
- coalesce overlapping tail refreshes without losing newer refresh demand
- improve cold-session loading by moving deferrable work out of the critical
bootstrap path
- isolate URL authentication, mobile credentials, native secrets, and other
runtime-owned state across endpoint changes
- bound long-lived caches and remove avoidable allocations from event and
rendering hot paths
- limit virtualization to archive collections where it improves rendering
without disrupting active sidebar layout
- stabilize session folders, pin ordering, expanded state, and persisted
sidebar behavior
- open skill files through the same secure editor and outside-workspace grant
flow used by file navigation, including worktree sessions
- expand regression coverage for stale completions, runtime collisions,
reconnect behavior, persistence races, authoritative empty results, and
subagent refresh ordering
- document the updated synchronization, cache ownership, performance, and
runtime-isolation invariants
* feat: added themes system
* feat: smart sidebar auto-hide for files/diff tabs + lower files sidebar threshold
* feat: added Checkbox component and update theming
- Add reusable Checkbox component for toggles across UI
- Replace several inputs with Checkbox in settings and commands panels
- Add DiffIcon and apply surface/border theming to key UI areas
* feat: Add convert-vscode-theme.cjs to convert VS Code themes to OpenChamber format
* refactor: remove unused permission logic from ChatInput
- Remove unused permission rules parsing logic from ChatInput
- Memoize renderTheme in DiffWorkerProvider to avoid unnecessary recalculations
- Remove forceOpaque helper in vscode theme adapter
* fix: guard VSCode theme loading in MarkdownRenderer
* feat: add custom user themes loading and reload
- Load user themes from ~/.config/openchamber/themes at runtime
- Expose /api/config/themes to fetch custom themes
- Allow theme reloading from Settings → Theme → Reload themes in the UI
