Garry Tan db38fd2c07 feat(browse): domain-skills storage + state machine
New module browse/src/domain-skills.ts implements the per-site notes
the agent writes for itself, persisted as type:"domain" rows alongside
/learn's per-project learnings.

Three scopes layered: per-project default, global by explicit promotion.
Project-active shadows global for the same host.

State machine (T6 — codex outside-voice):
  quarantined --3 uses w/o flag--> active(project) --promote--> global
        ^                                |
        +----- classifier flag during use

- Append-only JSONL with O_APPEND for atomic small writes
- Tolerant parser drops partial trailing line on read
- Tombstone for deletes (compactor cleans up later)
- Version log per (host, scope) enables rollback
- Hostname derived from active tab top-level origin (T3 confused-deputy fix)
- writeSkill rejects classifier_score >= 0.85 with structured error
