conductor(plan): mark Phase 1 complete (site inventory + classification)
TIER-2 READ conductor/code_styleguides/error_handling.md end-to-end before Phase 1.
Phase 1 covered:
- t1.1 [a068934]: Run audit --json, captured 77KB PHASE1_AUDIT.json
- t1.2 [a068934]: Wrote PHASE1_SITE_INVENTORY.md (42 rows; phase distribution
P3=8, P4=3, P5=13, P7=1, P8=4, P9=1, P10=8, P11=2, P12=2 = 42)
- t1.3 [554fbbd]: Created tests/test_gui_2_result.py with 2 invariant tests
(test_phase_1_inventory_has_42_rows + test_phase_1_audit_has_42_migration_target_sites)
- Phase 1 checkpoint: state.toml Phase 1 -> completed; 2 invariant tests pass.
Phase 1 establishes the migration-target scope. Phase 2 begins: drain plane
wiring (3 new render functions for the data plane consumer side).
