feat(ai-tools): omp shared + OpenCode/omp sessions, tokens, subagents; Grok hooks; resume by id

- omp-usage.js / opencode-usage.js: poll each CLI's own session store into
  sessions (tool omp/opencode), token_usage per model and subagent agents;
  transcript routes read them (omp journals, OpenCode's opencode.db).
- Grok runs the Claude hooks in ~/.claude/settings.json: its hooks are now
  recognised (hookEventName + workspaceRoot), tagged tool=grok, and their
  transcript_path dropped instead of being parsed as a Claude transcript.
- Catalog `resumeById`: omp/Grok/Cursor `--resume <id>`, OpenCode
  `--session <id>`; session ids may carry `_`. The client offers Resume for
  any tool that resumes by id.
- Kimi Code and GitHub Copilot leave the catalog (their session stores could
  not be verified).
