v3.22.0 — V5-4 process-seam adoption (developer-workflows 0.25.0)

MINOR — developer-workflows 0.24.0 → 0.25.0: V5-4 process-seam adoption. resolve_plan.py previously bridged directly to agentm/scripts/harness_memory.py resolve-active-plan — an informal reach-in predating the V5-4 process seam. Now that the seam has shipped in agentm (process_seam.py, agentm v5.2.0), the informal bridge is retired in favour of the designed interface. A new find_process_seam.py script (DC-2 compliant — best-effort discovery, graceful-skip to exit 1 when agentm absent) discovers process_seam.py via path-fallback, and resolve_plan.py now makes two seam calls (state-path plan + state-path progress) and reassembles the tab-separated pair. The output contract and exit codes are unchanged (callers see <plan_path>\t<progress_path> on stdout; exit 0/1/2); the seam-vs-fallback switch is fully internal.

Added

• developer-workflows 0.25.0 — find_process_seam.py: V5-4 seam discovery bridge. Discovers agentm's process_seam.py via $AGENTM_SCRIPTS_DIR → co-located sibling → ~/Antigravity/agentm/scripts/ path-fallback (mirrors find_capability.py's DC-2 pattern). CLI: find_process_seam.py state-path {plan|progress} [--plan SLUG] [--cwd ROOT]. Exit 1 when seam absent; graceful-skip, never hangs. Injectable seam= path for tests.

Changed

• developer-workflows 0.25.0 — resolve_plan.py migrated from harness_memory.py resolve-active-plan to two find_process_seam.py state-path calls. locate_resolver() retained for queue_status.py's agentm-scripts-dir lookup. Backward-compat resolver= alias in resolve() so downstream callers (design_doc, stage_plan, spawn_worker, integrate_worker) need no source changes.

Internal

• test_find_process_seam.py (16 tests): discovery via $AGENTM_SCRIPTS_DIR / co-located / conventional / absent; run_state_path plan+progress propagation; main() CLI usage; seam-absent graceful exits.
• test_resolve_plan.py updated: harness_memory.py stubs replaced with find_process_seam.py seam stubs; four delegate tests confirm tab-separated pair output and Risk #7 invariant.
• test_design_doc.py, test_spawn_worker.py, test_integrate_worker.py: stub-stderr assertions updated to assertNotEqual(err, "").
• test_obsidian_vault_discovery.py + test_obsidian_vault_doctor.py: fixture configs updated to the post-V5-7 plugin-namespaced key so agentm V5-7's first-read migration does not fire during the test run.
• Wiki: Named-Plans.md resolver bridge table and description updated for V5-4; Developer-Workflows.md notes find_process_seam.py alongside find_capability.py; Explanation.md stale pending→implemented status corrected.
