Reasonix v0.47.0

Desktop matures. The Tauri app picks up the polish it was missing —
About modal with one-click update check, KaTeX math rendering in chat,
window/tab/session/scroll restore across relaunch, /compact /retry /btw
/feedback slash commands, per-message copy + file-export actions, QQ
settings entry, platform-aware keyboard shortcut hints. The auto-updater
now reads latest.json from the R2 mirror so an npm-only v* release
can no longer brick the in-app update banner; the banner also surfaces
download progress while the bundle pulls. Universal Node is bundled on
macOS so Intel Macs stop blank-screening at launch.

TUI — composer round two. Composer keys and visuals re-align with
Claude Code: rounded border, status row at the bottom, input-box
background fill, left stripe on user card. ctrl+r toggles verbose
(reasoning + raw tool I/O); esc-esc opens a rewind picker over the
last 5s; u undo is now gated to the same 5s window so stale taps
can't revert. SGR mouse wheel is on by default again, IME cursor stays
glued to ▌, WelcomeBanner centers vertically on empty chats.

Search hardening. Regex now runs in a worker thread so a ReDoS
pattern can be terminated cleanly; worker deadline 5s → 60s and walk
deadline 15s → 120s for legitimately large repos. Tavily added as a
web_search backend — escape hatch when Mojeek 403s. search_content
gets a walk-level deadline and ESC preempts queued tool calls.

Claude-ecosystem compat. Reasonix now reads .mcp.json and
.claude/skills/ from the repo so existing Claude Code setups work
without a second copy; common skill fields (type/context/agent)
are aliased.

Other:

• feat(embedding) batch OpenAI-compat embedding requests to respect
  provider batch limits
• feat(memory) inject ancestor AGENTS.md into list_directory,
  not only read_file
• perf(session) skip cross-workspace jsonls + byte-scan line count
  — sidebar list ~10× faster
• feat(config) support pricing overrides and per-model rpm limits
• feat(dashboard) new / switch / delete sessions in-place, no CLI
  bounce
• fix(mcp) runtime schema validation for MCP server responses; ESC
  aborts hung handshakes during startup; surface the real bridge-
  failure reason in the dashboard
• fix(cli) preserve flash-preset auto-escalate semantics
• ci split desktop + npm releases into separate tag namespaces:
  v* → npm, desktop-v* → Tauri bundles
