fix(v0.6.4): rollback removes the proposal's ab-tracking entry

adam-rollback.mjs's docstring always claimed it "removes the ab-tracking entry
(so it doesn't re-trigger)", but executeRollback() never did. Consequence: a
rolled-back proposal kept being re-detected as `regressed` on every subsequent
/reflect, which triggered endless `not_found` rollback attempts (the applied
file is already gone) and noisy ## Regressions sections.

executeRollback now deletes the matching ab-tracking.jsonl row by proposal_id
after the move, preserving all unrelated rows. Surfaced by running ADAM's own
/reflect loop a second time (two zombie regressions: 2026-05-16-002 and
2026-05-22-001).

Tests: 138 -> 140 (rollback purges the entry by id; an unrelated entry is
preserved).

 ## What's new
 
+- **v0.6.4** — rollback now keeps its promise. `adam-rollback.mjs`'s docstring always claimed it "removes the ab-tracking entry (so it doesn't re-trigger)," but `executeRollback()` never did — so a rolled-back proposal kept flagging as `regressed` on every subsequent `/reflect`, triggering endless `not_found` rollback attempts. It now deletes the matching `ab-tracking.jsonl` row by `proposal_id` (preserving unrelated rows). Surfaced by running ADAM's own loop twice. 140 tests (up from 138).
 - **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).
