P5 — Overlay composer + cross-harness (`compose-contract`)

Implements R7 + R8 + the R9 composer test of the Constitution alpha. Closes #604 (lineage #542).

What it does

mosaic compose-contract <harness> and the launcher both produce one pre-merged contract blob with operator *.local.md overlays composed in (DESIGN §3.2), so a user's deltas reach the model without a read-merge ritual.

composeContract(runtime, mosaicHome=MOSAIC_HOME) — testable pure fn extracted from the launcher prompt assembly; buildRuntimePrompt delegates to it.
Overlay logic (deltas by value; base files keep residency):
- USER.local.md → appended under the # User Profile block (USER is injected).
- SOUL.local.md + STANDARDS.local.md → trailing # Operator Overlays section. Their bases are load-on-demand, so only the small delta is injected — preserves the P3 byte-budget tiering. Whitespace-only overlays ignored.
- Absent *.local → base-only, automatically.
New command mosaic compose-contract <harness> → prints the composed blob to stdout (inspection / mosaic doctor / diffing / the composer test). Validates the harness.
defaults/AGENTS.md bare-launch self-load fallback now nudges to relaunch via mosaic <harness> (or mosaic doctor) when overlays exist (R7 known-limitation, §9).

ASSUMPTION (steered autonomy)

Overlays are injected as deltas by value under labeled sections; bases keep existing residency (USER injected; SOUL/STANDARDS load-on-demand). Rationale: honors §3.2 without re-injecting large base prose / breaking the P3 byte budget. Full reasoning in docs/scratchpads/p5-overlay-composer.md.

Verification

compose-contract.spec.ts — 7 tests: per-tier anchors, Tier-3 byte-equality (injected L0 == CONSTITUTION.md on disk), overlay present/absent, whitespace-only ignored, per-harness runtime selection. ✅
launch.spec.ts — 26 existing tests still green (refactor regression). ✅
tsc clean on touched files; prettier clean; pnpm lint/typecheck pass.

Note for the reviewer

Commit 9f6da92 is a separate chore(format) fixing a pre-existing repo-wide format:check violation on main (docs/fleet/PRD-fleet-suite.md, markdown-table alignment only — no content change). It was blocking the pre-push gate; picked it up to unblock. Easy to drop/attribute separately if you'd rather handle it in the fleet-suite lineage.

feat(mosaic): P5 overlay composer — compose-contract + *.local overlays (#604 ) bca7fc4cf2

Implements R7 + R8 of the Constitution alpha: launcher-composed operator
overlays so a user's *.local deltas reach the model as one pre-merged blob
(DESIGN §3.2), without re-injecting full base prose.

- composeContract(runtime, mosaicHome=MOSAIC_HOME): testable pure fn extracted
  from the launcher prompt assembly; buildRuntimePrompt delegates to it.
- Overlay logic (deltas by value, base files keep residency):
  - USER.local.md -> appended under the # User Profile block (USER is injected)
  - SOUL.local.md + STANDARDS.local.md -> trailing # Operator Overlays section
    (their bases are load-on-demand; only the small delta is injected, so the
    P3 byte-budget tiering is preserved). Whitespace-only overlays ignored.
  - Absent *.local -> base-only, automatically.
- New command: mosaic compose-contract <harness> -> prints the composed blob
  to stdout (inspection / mosaic doctor / diffing / the composer test).
- defaults/AGENTS.md: bare-launch self-load fallback now nudges to relaunch via
  mosaic <harness> (or mosaic doctor) when *.local overlays exist (R7 known-limit).
- compose-contract.spec.ts (7 tests): per-tier anchors, Tier-3 byte-equality
  (injected L0 == CONSTITUTION.md on disk), overlay present/absent, per-harness.

ASSUMPTION: overlays injected as deltas-by-value under labeled sections; bases
keep existing residency. Rationale in docs/scratchpads/p5-overlay-composer.md.

Verified: 7 composer + 26 launch tests pass; tsc-clean on touched files;
prettier clean. Defers to P6: CONTRIBUTING.md + compliance matrix, line-count
CI ceiling, aiguide reconcile, alpha tag.

Pre-existing repo-wide format:check failure on origin/main (markdown table
alignment only — no content change). Picked up to unblock the pre-push gate;
flagged to the Lead. Not part of the P5 composer change.
