v0.2.0: drop cursor, add source_entries lifecycle, mandate memory frontmatter

Lifecycle redesign:
- Each proposal records source_entries: [<ts>...] in frontmatter listing
  the journal timestamps that fed its cluster.
- After apply/reject, skill calls adam/scripts/adam-archive.mjs which moves
  matching entries from journal.jsonl to journal/actioned-<id>.jsonl.
- Agent reads applied/ + rejected/ frontmatter on each /reflect, builds an
  excluded-timestamps set, skips any leftover already-actioned entries.
- cursor field in state.json is vestigial; agent ignores it.

Effect: journal stays bounded by active observations. Rule changes
re-evaluate the remainder without manual rewind. Race-safer for parallel
sessions on shared state.json (no cursor write contention).

Memory drafting:
- agents/adam.md adds 'Memory drafting protocol' parallel to Skill drafting.
- Memory proposals MUST contain auto-memory frontmatter (name, description,
  type, originSessionId) in '# Proposed change' body.
- Skill enforces frontmatter check at apply time; refuses if missing.

Tests: 18 -> 21. Two new tests for adam-archive happy path + no-op.

Migration: existing applied proposals lack source_entries. Their backing
journal entries archived as a one-time bulk migration; legacy proposals
annotated with migration note.
