feat(v0.6.3): release-update notifier (notify-only, SessionStart)

Adds a lightweight "new release available" notice without auto-installing —
because re-running install.sh overwrites ADAM's own /reflect-applied skill
edits, so the user must choose when to take an update.

- install.sh writes ~/.claude/adam/.version (the installed release tag) on
  every install. Derived from $VERSION / piped REF / `git describe --tags`.
- adam-nudge.mjs (SessionStart) compares .version against the latest GitHub
  release at most once/day. Cached in ~/.claude/adam/.update-check.json; the
  cache drives an instant nudge (no network on the hot path) and is refreshed
  best-effort with a 1.5s AbortController cap. fetch unavailable / offline /
  timeout / rate-limit / parse error all degrade to silent no-op. Opt out with
  ADAM_NO_UPDATE_CHECK=1. main() is now async; never blocks SessionStart.
- README: "Staying up to date" section; pin example bumped to v0.6.3.

Tests: 134 -> 138. Notifier verified fully offline (cache-driven): nudges when
a newer release is cached, silent when current, suppressed by the opt-out env,
and no-ops when the .version marker is absent.

```
### Staying up to date
`install.sh` records the installed release in `~/.claude/adam/.version`. The
SessionStart hook (`adam-nudge.mjs`) then checks the latest GitHub release **at
most once a day** (cached in `~/.claude/adam/.update-check.json`, network call
hard-capped at 1.5 s, fully best-effort — it never blocks or slows session
start). When a newer release exists it prints a one-line, **notify-only** prompt:
```
[adam] update available: v0.6.3 → v0.6.4. Apply: curl -fsSL …/install.sh | bash
(re-runs install.sh — resets ADAM's own /reflect-applied skill edits; apply when you're ready)
```
It is deliberately **not** auto-applied: re-running `install.sh` overwrites
ADAM's own `/reflect`-applied skill edits, so you decide when to take an update.
Disable the check entirely with `ADAM_NO_UPDATE_CHECK=1` in your environment.

## What's new
- **v0.6.3** — release-update notifier. `install.sh` now writes a `~/.claude/adam/.version` marker; `adam-nudge.mjs` (SessionStart) compares it against the latest GitHub release at most once/day (cached, 1.5 s network cap, best-effort — never blocks) and prints a **notify-only** one-line update prompt. Deliberately not auto-applied: re-running the installer resets ADAM's own `/reflect`-applied skill edits, so you choose when to update. Opt out with `ADAM_NO_UPDATE_CHECK=1`. See "Staying up to date". 138 tests (up from 134).
- **v0.6.2** — two fixes surfaced by running ADAM's loop on a large real journal. **(1) A/B volume normalization** (`adam-ab-measure.mjs`): regressions are now measured on the signal's *share* of total activity (rate = count / window-total), not raw count — so a generally busier journal after an apply no longer masquerades as a regression. Falls back to raw delta when the signal is the only activity in the window (preserves prior behavior + tests); output adds `raw_delta_pct`, `pre_total`, `post_total`, `normalized` for transparency. **(2) Memory frontmatter schema** (`agents/adam.md`, `SKILL.md`): the drafting protocol now emits the live auto-memory shape — `name` = slug + a `metadata: {node_type, type, originSessionId}` block — instead of flat `type:`/`originSessionId:`, so auto-applied memories load and categorize correctly. 134 tests (up from 132).
- **v0.6.1** — new `file_reread` signal (MOSS §1 harness self-modification, proposed and approved through ADAM's own `/reflect` loop). Consecutive Reads of the same file at different `offset`/`limit` escaped `retry_loop`'s arg-hash dedup and leaked into `tool_error_loop`; `file_reread` now catches them (same file ≥3× in the 10-event window, offset-agnostic, guarded against double-counting byte-identical reads). Fully wired: detection (`adam-observe.mjs`), 14-day window (`adam-window.mjs`), severity divisor 3 (`adam-score.mjs`), file-basename clustering (`adam-batch.mjs`), and the analyst rubric/spec. 132 tests (up from 126).
- **v0.6.0** — review hardening. Struggle signals now emit `active_skills`, so `silent_drift`'s primary cluster key and the §5b skill-attribution sub-clustering (+1 rubric bonus) actually fire (both were silently dead). `proposal_fingerprint` is now deterministically computable via `adam-cooldown.mjs --compute` instead of asking the LLM analyst to hand-compute a djb2 hash; spec now mandates a *stable* cluster id so fingerprints reproduce across runs. `reinforcement` proposals are correctly excluded from A/B tracking (the spec previously contradicted itself). `adam-nudge.mjs` pending-upgrade check now mirrors the full install set (`adam-utils`/`adam-batch`/`adam-rollback` were missing). Doc/test-count drift corrected. 126 tests (up from 114).
