🔧 Worktree-Aware Planning

/start-work now accepts --worktree — Prometheus creates plans that know which worktree they belong to. Atlas picks up the worktree path in boulder continuation. Parallel feature branches without stepping on each other.

🧠 Smarter Model Routing

Gemini 3 → 3.1 Pro across the board. GPT model detection simplified to name-based matching — cleaner, faster, no more edge cases with o-series. Kimi added to writing category fallback. Hephaestus auto-commit behavior removed — agents no longer commit without your explicit request.

🛡️ Reliability Hardening

Every major control loop got hardened:

• Ralph Loop: Completion detection scoped to messages since loop start. In-flight guard prevents infinite re-trigger. Race condition between session reset and TUI switch eliminated.
• Todo Continuation: Blocked todos excluded from incomplete count — no more infinite loops on dependent tasks.
• Background Agent: Notification queue for idle sessions. Pending notifications cleaned on session delete.
• Token Limiter: Truncation now respects newline boundaries. No more mid-line cuts in delegated prompts.
• Compaction: Timeout + cleanup prevents indefinite hangs during rate limiting.

📊 Hashline Edit Benchmarks

New benchmark suite (46 tests) for hashline-edit contributed by @minpeter. Deduplication and validation fixes. Diff context limited to 3 lines to prevent oversized hunks.

🖥️ Platform & Compatibility

Windows: windowsHide on all Bun.spawn calls — no more stray terminal windows. Legacy hardware: baseline CPU variant binaries added. Config: existing user settings preserved when writing new defaults. Formatter config no longer silently dropped.
