emrg: sync Agent.md Python test count to 1003 (doc-count guard fix for commit 463c2bb)

[argszero]

Fix the post-463c2bb CI failure: the doc-count guard (tests/test_doc_counts.py::test_python_count_matches_docs) fails on master because commit 463c2bb added 2 tests (TestStopAllSkipGui in tests/test_main.py) but Agent.md still documents 1001.

• Collected: 1003 (1002 passed + 1 skipped locally)
• Agent.md line 121: (1001) → (1003)
• Doc-only change; restores master CI (test + test-windows) to green

[argszero]

✅ LGTM — cycle. Doc-only fix: Agent.md Python test count 1001 → 1003 (syncs the post-463c2bb +2 tests); verified locally 1002 passed + 1 skipped (1003 collected); CI test + test-windows PASS (run 32495085112). Restores master CI to green after the direct-push commit 463c2bb skipped the doc sync.

✅ LGTM — cycle 1229. Re-verified: 1-file doc-only diff (Agent.md 1001 → 1003), head unchanged; CI test + test-windows PASS (run 32495085112). This is the canonical minimal fix for the post-463c2bb master CI-red (doc-count guard). 2/3 LGTMs.

[argszero]

✅ LGTM — cycle 1230. Head 8b4e95b unchanged; doc-only Agent.md count sync 1001 → 1003; CI test + test-windows PASS (run 32495085112). 3rd consecutive LGTM (cycles 1228 → 1229 → 1230), no ❌ in between — merge condition satisfied.
