Fix QQ bot approval and Weixin stale session detection

[TKwave]

Fixes #35760, #35713

Changes

fix(#35760): support dm chat_type in QQ bot approval authorization

• QQ bot approval buttons were always rejected because session uses 'dm' chat_type
• Changed to match both 'c2c' and 'dm'

fix(#35713): treat 'rate limited' as stale session signal in Weixin adapter

• 'rate limited' error with ret=-2 was being treated as genuine rate limit
• Added 'rate limited' to stale session signals alongside 'unknown error'
• Prevents burning retries against dead context_token

[alt-glitch]

The QQ bot DM auth fix duplicates open #35774. The Weixin stale-session fix duplicates open #35714. This PR also bundles unrelated changes: runtime footer live CWD (gateway/run.py, gateway/runtime_footer.py, tools/terminal_tool.py) and skill tool robustness fixes (tools/skill_manager_tool.py, tools/skills_tool.py). Consider splitting into focused PRs.

Review Findings

✅ Looks Good — Four Independent Fixes

1. QQ Bot approval: support dm chat_type (qqbot/adapter.py)

• chat_type in ("c2c", "dm") — correct fix for the approval authorization mismatch. Simple one-line change.

2. Weixin stale session: treat 'rate limited' as stale signal (weixin.py)

• (errmsg or "").strip().lower() — defensive normalization.
• Empty errmsg now treated as stale (return True) — sensible default.
• "rate limited" added to stale signals alongside "unknown error" — prevents burning retries against dead context tokens.

3. Runtime footer: live CWD from task env overrides (run.py, runtime_footer.py, terminal_tool.py)

• get_task_cwd() returns live cwd from _task_env_overrides — correctly handles the case where TERMINAL_CWD is stale.
• session_key threaded through build_footer_line → format_runtime_footer.
• The fallback chain cwd > live_cwd > TERMINAL_CWD is correct.
• get_task_cwd() returns None if no overrides exist, so the fallback chain degrades gracefully.

4. Skill tool fixes:

• (skill_manager_tool.py) file_content/content fallback: LLMs sometimes pass content to the wrong parameter. The fallback logic (content = file_content for create/edit, file_content = content for write_file) correctly handles this without silent data loss.
• (skills_tool.py) Asset-in-skill-directory guard: prevents treating templates/foo.md inside a skill directory as a standalone skill. The while parent != search_dir walk correctly walks up the tree to check for parent SKILL.md files.

No issues found. All four fixes are well-scoped, correct, and cleanly implemented.
