fix: resolve ruff lint errors in hermes and openharness adapters (#1458)

## Summary

- Remove unused imports (`os`, `Dict`, `List`) and add `contextlib`
where needed
- Replace `try`-`except`-`pass` patterns with `contextlib.suppress()`
for cleaner error suppression (SIM105)
- Use list unpacking `[*tsx.split(), str(candidate)]` instead of
concatenation (RUF005)
- Use `with open(...)` context manager for file handling in
`daemon_manager.py` (SIM115)
- Add `# noqa: E402` for intentional late imports after `sys.path`
manipulation
- Replace deprecated `typing.Dict`/`typing.List` with builtin
`dict`/`list` (UP035)

All 20 remaining ruff lint errors resolved. `ruff check
apps/memos-local-plugin` now passes cleanly.

## Files Changed

- `adapters/hermes/__init__.py`
- `adapters/hermes/bridge_client.py`
- `adapters/hermes/config.py`
- `adapters/hermes/daemon_manager.py`
- `adapters/openharness/scripts/bridge_client.py`
- `adapters/openharness/scripts/config.py`
- `adapters/openharness/scripts/daemon_manager.py`

## Test Plan

- [x] `ruff check apps/memos-local-plugin` passes with no errors
- [ ] Verify hermes adapter still loads and functions correctly
- [ ] Verify openharness adapter still loads and functions correctly
