hermes plugins install <repo>#gateway-plugin ships ONLY the
gateway-plugin/ subdirectory into ~/.hermes/plugins/iris, so the
repo-root VERSION file is not present there and plugin_version()
fell back to 'unknown' — the app then showed a false
'App and gateway versions differ' warning.
- version.py: resolution chain repo-root VERSION (dev/symlink
install) -> plugin.yaml version field (production install) ->
'unknown'; stdlib-only parse, base= param for tests
- plugin.yaml: bump stale version 0.1.0 -> 0.1.2 (matches VERSION)
- scripts/check_version_sync.sh + pre-commit hook: fail commits
where plugin.yaml drifts from the repo-root VERSION
- tests: regression test simulating the production layout
