* refactor(plugins): remove the Sep 2026 decomposition compat layer on schedule The PLUGIN-COMPAT layer (2776813df3+d63e380324+0a5164cebe) kept pre-#102117 import paths alive for external plugins until 2026-09-14. That window closed two weeks ago; since then the loader has already been skipping plugins that use the old paths. This removes the layer itself: - 328 appended `PLUGIN-COMPAT` blocks (lazy `__getattr__` pointer tables, re-exported third-party names, restored dead definitions) and the three re-export stub modules (gateway/startup_watchdog, hermes_cli/observability/relay_runtime, tools/environments/modal_utils) - COMPAT_MANIFEST.md, compat_manifest.json, scripts/check_compat_pointers.py and its lint step - the reporting surfaces: CLI banner notice, `hermes plugins compat`, the `hermes doctor` section, the post-update notice, the Desktop one-time dialog, the loader's pre-import skip and the `plugins.allow_deprecated_imports` escape hatch An external plugin that still imports an old path now fails to load with its ImportError as the reason in `hermes plugins list`, the same path as any broken plugin. hermes_cli/plugin_compat.py stays as three inert stubs (compat_report, removal_in_effect, summary_lines): an already-running pre-removal `hermes update` lazy-imports them after the checkout swap (tests/compat/old_updater_surface.json). In-tree fallout, both already dead: hermes_cli/setup.py::_check_espeak_ng (no callers; its `shutil` came from a compat block) and gateway/config.py::SessionResetPolicy ("retained solely for the scheduled plugin-compat window"). Two test_run_agent patches targeted the removed `run_agent.handle_function_call` pointer; they now patch `model_tools.handle_function_call`, the seam production reads, like every sibling test in that file. * chore: retrigger CI (zero-job startup_failure phantom) * test: drop resolution allowlist rows for the two deleted which() sites hermes_cli/setup.py::_check_espeak_ng (dead) and tools/skillevaluator_scan.py::scanner_available (a restored definition inside a PLUGIN-COMPAT block) no longer exist; the stale-row gate requires their allowlist entries go with them.
