feat(project-development): parallel-writer follow-up — triple-disjoint contract, native report delivery, SHA bump

[LeXwDeX]

Closes the config side of OpenCode-GraphAgent issue #295.

Summary

The runtime merged real parallel workspace writers with an implementation aggregator (OpenCode-GraphAgent PR #299, merge SHA ebc5ad08). This change completes the config-repo side required by the incompatible-block-rule policy: runtime first, then SHA bump and affected templates in the same change.

Change

• runtime-compat.json: pin runtime_commit to ebc5ad089c782c7c4f2a128d4def41a75103f175 (the parallel-writers merge).
• project-development-full.yaml plan block: parallel slices now run concurrently in one workspace, so the instruction carries the triple-disjoint write-set contract (source files, generated artifacts, and lockfiles disjoint; no shared build; delivery/artifact-wiring slices kept separate from source-only slices).
• project-development-full.yaml report block: replace the hand-rolled temp-dir DELIVERY CONTRACT with the runtime's native output-by-reference (submit the absolute report path under the project .opencode/workflow-reports/ area; the runtime records the file reference with its integrity receipt).

Verification

• Local route-catalog validation green (14/14 routes across 7 full/lite domains).
• CI template validation runs the runtime-owned validator checked out at the pinned SHA — it exercises the new block compiler (aggregator expansion, rewired verify) against every route.
