Address Copilot's 6 findings on PR #1242:

5x P1: Bump last_updated to 2026-05-02 on each touched row
(B-0003, B-0006, B-0058, B-0060, B-0061). Schema requires
last_updated bump on every content edit per
tools/backlog/README.md:67.

1x P1: Document depends_on in the published schema. Adds row
to the Frontmatter-fields table + adds depends_on:[] to the
example frontmatter block. Notes the distinction from
composes_with (depends_on = ordering / hard prerequisite;
composes_with = cross-reference / bidirectional). Notes the
backfill-discipline (incremental on-demand) per Aaron
2026-05-02. Notes that the field is graph-traversal-only
(not surfaced in BACKLOG.md index — index stays scan-fast,
DAG queries consume frontmatter).

Composes with PR #1238 batch 1 (already merged): same class
of finding existed there but was not addressed before
auto-merge; this PR now closes both gaps for the batch 2
rows + retroactively for the schema doc.

…e review-cycle resolution

PR #1241 (never-idle 2nd + 3rd refinements) + PR #1242
(depends_on backfill batch 2) both went through the
BLOCKED-with-green-CI investigate-threads-first discipline
this tick. 9 Copilot findings total resolved across the two
PRs.

Coverage: 16/160 → 21/160 backlog rows have depends_on
populated. Schema doc updated to canonically document the
field (closing a retroactive gap from PR #1238 batch 1).

* backlog(depends-on): batch 2 — backfill depends_on:[] on 5 P1 rows

Continues incremental on-demand backfill from PR #1238 (batch 1).
Adds depends_on:[] field between last_updated: and composes_with:
on 5 P1 rows touched in recent ticks:

- B-0003 alignment-md-rewrite
- B-0006 memory-md-compression-pass
- B-0058 ai-ethics-and-safety-research-track
- B-0060 human-lineage-external-anchor-backfill
- B-0061 finish-monolith-to-per-row-migration

Empty value preserves the no-known-dependencies default; explicit
field unblocks graph traversal tooling that would otherwise treat
missing-field as unparseable rather than empty.

Coverage advances 16 → 21 rows out of 160. Index unchanged because
generate-index.sh doesn't surface depends_on (graph-traversal
field; not human-scan field).

Composes with the aperiodic-tiling-as-strange-attractor framing
from never-idle memo refinements (PR #1241): backlog rows are
the tiles, depends_on is the local-adjacency relation that makes
the tiling computable.

PR #1238 (depends_on backfill batch 1) merged with Copilot's
last_updated-bump finding un-addressed; same finding fired
on PR #1242 batch 2 and got fixed there. Aaron 2026-05-02
correction: "the answer to if it matters is almost always
yes in real life lol" — closing the gap retroactively rather
than leaving as a backlog item.

Bumps last_updated to 2026-05-02 on:
- B-0062 wallet-v0-build-out (was 2026-04-28)
- B-0109 dependency-status-tracking-surface (was 2026-04-30)

The depends_on backfill on these rows IS a content edit per
the schema rule (tools/backlog/README.md:67); the bump
restores per-row metadata consistency.

Composes with PR #1242 schema-doc update (depends_on now
documented) and PR #1242 batch-2 last_updated bumps. Same
discipline applied uniformly across batch 1 + batch 2.

…on all 139 remaining rows (#1246)

Concentrated effort per the human maintainer 2026-05-02:
"depends_on first to be safe, it won't take long, feel
free to direct an effort here if you want instead of
trickle in."

Adds depends_on: [] (no-known-dependencies default) to every
backlog row that lacked the field. Coverage 21/160 → 160/160.

Mechanical work via /tmp/backfill-depends-on.sh: insert
depends_on:[] after last_updated:; bump last_updated to
2026-05-02 (per schema rule: every content edit bumps the
date — same rule that fired on PR #1242 and PR #1243).

This PR does SCHEMA COMPLETION, not RELATIONSHIP ANALYSIS.
The honest depends_on for the bulk of these rows is empty
(independent capability additions / audits / refactors).
The minority that have hard prerequisites need per-row
analysis to identify them correctly — that's a separate
ongoing pass, incremental as rows are touched.

What this PR enables:
- Graph-traversal tooling iterates without missing-field crashes
- No-known-dependencies state is now explicit (committed by author)
- Field exists at the write target for relationship-analysis pass
- Precondition for parallel-tracks dispatcher unblocked (field present;
  field-correctly-filled is the separate ongoing work)

Composes with:
- PR #1238 (batch 1 — first 2 P0 rows; same pattern)
- PR #1242 (batch 2 — 5 P1 rows; surfaced the schema-doc gap)
- PR #1243 (batch 1 retroactive last_updated bump)
- PR #1244 (B-0109 first iteration; this row also got depends_on
  via that PR)

BACKLOG.md regenerated; no diff (generate-index.sh doesn't
render depends_on per the scan-fast-vs-graph-traversable
separation).
