fix(tg-gateway): dedupe skill bundle, unpin engine model, add claude … - #8

…reset runbook

Operator report 2026-07-27: molyanov commands unreliable from Telegram
(alias mismatch, agent doesn't recognize them at once), no way to change
engine or reset/relogin Claude after quota exhaustion.

Fixes in this repo's scope:

- claude-skills bundle: remove the 17 underscore-duplicate skill dirs
  (code_reviewing etc.) — they carried IDENTICAL frontmatter name: values
  as their dash twins, so every deployed session saw duplicate-skill
  conflicts and resolution became unreliable. Dash dirs are canonical;
  command files keep both spellings (Telegram only allows [a-z0-9_] in
  bot commands). Convention documented in files/claude-skills/README.md.
- telegram-ai-agent role: purge already-deployed underscore skill dirs
  from both engine HOMEs (skills sync is additive), driven by
  telegram_ai_agent_legacy_underscore_skills in defaults.
- molyanov role: stop symlinking the raw upstream bundle as nested
  ~/.claude/skills/molyanov-ai-dev — Claude Code resolves personal skills
  at ~/.claude/skills/<name>/SKILL.md, so the nested tree was either
  undiscovered or a second duplicate source; remove the legacy link on
  deploy. Clone at /opt/molyanov-ai-dev stays for reference/diffing.
- config.yml.j2: engine model no longer hardcoded (claude-opus-4-1) —
  telegram_ai_agent_claude_model / _codex_model vars + per-topic model
  override, so a quota-driven model switch is a one-var redeploy. Also
  fix latent trim_blocks newline bug that glued 'topics:' and 'model:'
  onto preceding lines whenever the topic matrix was non-empty.
- new bot-claude-reset helper (/usr/local/bin): stop bot, kill stray
  claude/MCP processes, optionally wipe session-resume state and rotate
  CLAUDE_CODE_OAUTH_TOKEN / ANTHROPIC_API_KEY in .env, restart. This IS
  the relogin path — bot auth comes from .env, not claude /login. README
  runbook added.
- work/tg-slash-command-gateway/user-spec.md: spec for the bot-fork side
  (mnemonik-dev/telegram-ai-agent): command discovery + setMyCommands
  registration, dash/underscore alias normalization, native command
  mapping (/clear /model /status), /engine switching incl. General chat,
  in-chat /relogin. Fork is not reachable from this session.
