chore: 2026.10.0

[fylorn]

Release PR for ThinkWatch Lite 2026.10.0. It has two commits:

1. Use core v0.57.1.
   • Core 0.57.1 (ThinkWatchProject/ThinkWatch-Core#248) answers requests other than POST with a 404 instead of forwarding them as empty POSTs.
   • Hermes Agent's start-up checks for a local model server are therefore no longer recorded. The adoption note that said they appear in Traffic as failed requests is removed: code, translation and screenshot mock.
   • The new core code gw.method.not_forwarded gets its Chinese sentence.
   • Protocol (31) and schema (23) are unchanged from 0.57.0.
2. chore: 2026.10.0.
   • Version bump in the four files.
   • release-notes/2026.10.0.md for the release page. It covers everything since v2026.9.26: whole-history and content search, the upstream check-up, ID and card redaction, Pi / oh-my-pi / Grok Build / Qwen Code / Hermes Agent, getting-started guidance, and requests other than POST.

The version follows the calendar: the first release in October is 2026.10.0, after 2026.9.26. Version comparison in the updater, Homebrew and Info.plist orders it after 2026.9.26.

Upgrade check

• Config parsing is unchanged between core 0.56.0 and 0.57.1: only doc strings in tw-config, and 0.57.1 touches tw-gateway only.
• A config written by 0.56.0 twcore init, and a copy of a real local config, both pass twcore check. The copy was deleted afterwards.
• The release notes say that request history is cleared (schema 23) and that a remote core must be 0.57.x.

Checks

• scripts/version.sh → 2026.10.0; cargo metadata --locked --offline; release_notes_test.py
• pnpm typecheck, vitest (611 tests)
• cargo fmt --check, clippy --all-targets -D warnings, cargo test: 760 passed, with control_plane re-run against the published twcore 0.57.1
• msg_codes and ts_bindings regenerated: msg-codes.txt loses one line, tw-api.ts unchanged
