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.

## Lifecycle: how proposals become permanent
Every proposal records the journal entry timestamps that fed its cluster (`source_entries` in frontmatter). When you apply or reject a proposal, the skill calls `adam/scripts/adam-archive.mjs` which moves matching entries from `journal.jsonl` to `journal/actioned-<id>.jsonl`. Effects:
- The `journal.jsonl` stays bounded by **active** observations only.
- The next `/reflect` reads applied/ + rejected/ frontmatter, builds an excluded-timestamps set, and skips any leftover journal entries that were already actioned.
- Rule changes (e.g. lowering a threshold) immediately re-evaluate the remaining active observations — no manual cursor rewind needed.
## What it will not do
- No background LLM spend. The analyst runs only when you invoke `/reflect`.

b. List `applied_dir/` filenames. Parse each frontmatter `type`, `target`, `source_entries`. Tally `applied_by_type[type]`.
c. Compute the **excluded-timestamps set**: union of all `source_entries` arrays across `applied_dir/` + `rejected_dir/`. Journal entries with these `ts` values have already been actioned and MUST NOT be re-clustered.
d. Build the **rejected-ideas set** (token-tokenized `# Why` content) for fuzzy fallback matching when a new cluster topic resembles a rejected one but doesn't share `source_entries` (handles legacy proposals without `source_entries`).
e. Compute **type biases**:
- Types with applied:rejected ratio >2:1 (over ≥3 total): neutral, no bonus.
- Types with applied:rejected ratio <1:2 (over ≥3 rejections): **-1 confidence penalty**, recorded in proposal `# Why` as "type-bias-penalty: <reason>".

## Memory drafting protocol (for `memory` proposals)
Every `memory` proposal's `# Proposed change` section MUST contain the COMPLETE memory file body — frontmatter + content — that will be written to the target path under `~/.claude/projects/<encoded-home>/memory/<slug>.md`.
Required structure:

type: user | feedback | project | reference
originSessionId: <session_id from journal entries that fed this cluster>

- project: lead with fact/decision, then **Why:** and **How to apply:** lines.
- user: brief description of role/preference/knowledge.
- reference: pointer to external system + what's there.>
