Compact CLI and MCP output by default

[andrei-hasna]

Summary

• Make noisy CLI surfaces compact by default: hooks list, hooks search, hooks docs, and log list/search/tail/errors now show capped, scannable summaries with detail hints.
• Add gradual-disclosure paths via --limit, --all, --verbose, existing --json, hooks info <name>, and full docs with hooks docs <name> --verbose.
• Make MCP list/search/docs/registered/profile/log/agent tools compact by default with explicit compact:false or verbose:true full-detail escape hatches.
• Keep machine-readable/full-detail behavior covered by tests, including preserving the legacy 50-row default for full MCP log rows.
• Use bun:sqlite directly for the local hook event DB so tsc --noEmit uses the DB type expected by migrations/retention.

Before / After

Worst noisy command captured before this branch:

hooks docs checkbugs: 157 lines before -> 19 lines after
hooks list:            62 lines before -> 25 lines after
hooks search check:    27 lines before -> 15 lines after

Current hooks list default now starts as:

Available hooks (39, showing 20):

  gitguard          [PreToolUse Bash] Git Safety
  branchprotect     [PreToolUse Write|Edit|NotebookEdit] Git Safety
  checkpoint        [PreToolUse Write|Edit|NotebookEdit] Git Safety
  ...

  Showing a compact subset. 19 more hidden; use --limit, --all, --verbose, or hooks info <name>.

Current hooks docs gitguard now previews useful content instead of dumping the full README:

README Preview:

  Claude Code hook that blocks destructive git operations.

README has 31 lines. Use hooks docs gitguard --verbose for the full README, or --json for machine-readable output.

Compatibility

• Existing CLI --json paths for list/search/docs remain full machine-readable outputs.
• MCP tools now default compact, but full-detail paths are explicit and tested with compact:false or verbose:true.
• Adversarial review found a compatibility issue where full MCP log outputs would have defaulted to 20 rows; fixed by keeping 20 compact rows but preserving the legacy 50-row default for compact:false.

Validation

• bun run typecheck
• bun test (660 pass, 0 fail)
• bun run build

Adversarial reviewer focused on CLI compatibility, output ergonomics, and token bloat; required findings were reconciled before opening this PR.
