V3.8.5 — Command result cards

See also: docs/release-notes-v3.8.5.md

Fixed

• Fixed the always-allowed slash-command path: when Hermes executes /new, /reset, /clear, /undo, /stop, or direct /model <model> without asking for confirmation, Feishu/Lark now receives the command result as an interactive card instead of gray native text.
• Removed the extra direct message.update attempt for interactive command-card callbacks. Feishu callback responses now own the in-place card update, avoiding invalid msg_type=interactive update warnings.
• Updated the Gateway hook patch so Feishu command-card installation receives the current event, allowing command result cardification without touching unrelated normal replies.

Changed

• /update remains intentionally outside command-result cardification, preserving Hermes' background upgrade behavior.
• Patcher upgrade handling accepts the V3.8.4 command-card hook block and rewrites it to the V3.8.5 event=event form during install.

Tests

• Added regression coverage for always-allowed /new command result cards, one-shot command-result context consumption, /update plain-text preservation, callback-only command-card updates, and legacy command-card hook upgrade compatibility.
