Mathias bc011cc1f0 feat(claudewatcher): ingest Claude Code session transcripts into brain ...

New package internal/claudewatcher. The volume gate (24 turns/week of
agentsquad logs vs 500/week gate) exposed that the real signal lives
in daily Claude Code usage at ~/.claude/projects/*/<uuid>.jsonl, not
in agentsquad output. This package captures that signal. See infra#73
Track E + hyperguild#27 for the full reframe.

Components:
- parser: tolerant JSONL parser over the observed Claude Code session
  schema (user / assistant / attachment / system + bookkeeping types).
  Skip-flag fast-paths queue-operation, last-prompt, permission-mode,
  ai-title, bridge-session, file-history-snapshot.
- scrubber: 11-rule fail-closed regex set for credential shapes
  (bearer, postgres URIs, PEM, ssh-key, ghp_/sk-/sk-ant-/AKIA, homelab
  env tokens, SOPS markers). Drop turn + log on match.
- cursor: postgres-backed claude_session_cursors table, keyed by
  (host, file_path) with byte_offset. Resumable across pod restarts.
- watcher: poll loop. Walks SessionsDir, processes each .jsonl from
  its cursor offset, runs scrubber, emits a Batch per file to a
  Sink interface, advances cursor on successful Ingest.

No classifier integration in this commit — every kept turn is emitted
in a per-session batch. The cmd/server wiring (next commit) routes
batches to brain/wiki/claude-sessions/facts/. Classifier-driven hall
routing (decisions / failures / hypotheses) is a follow-up.

19 unit tests across parser + scrubber + watcher. task check green.
