[WIP] Add API for resolving target branch at runtime

[Copilot]

• Understood the full architecture (MCP call time vs apply time, manifest vs getBaseBranch)
• Implemented the fix in safe_outputs_handlers.cjs — step 4 in base branch resolution honors the agent's base arg when allowed_base_branches is configured
• Wrote 5 new tests for the dynamic base branch override feature
• All 190 tests in safe_outputs_handlers.test.cjs pass
• make fmt-cjs && make lint-cjs passes
• make agent-report-progress passes (all workflow lock files in sync, zero lint errors)
• parallel_validation (code review + CodeQL) — pending
• Add changeset file for the minor feature addition
