## Description
On Windows, `Path.read_text()` and `open()` default to the system locale
encoding (cp1252, GBK, etc.) instead of UTF-8. This causes
`UnicodeDecodeError` when reading or writing instruction files that
contain multi-byte UTF-8 characters such as smart quotes or em dashes.
The RTK instructions block itself contains an em dash (U+2014, `—`), so
`_inject_rtk_instructions` crashes on any non-UTF-8 Windows locale when
writing to `.copilot_instructions`, `.clinerules`, `AGENTS.md`, or
similar hint files.
Closes#1126
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- Add `encoding="utf-8"` to all bare `read_text()`, `write_text()`, and
`open()` calls in `headroom/cli/wrap.py` that handle instruction or
config files (18 call sites)
- Update test assertions in `test_wrap_hintfile_agents.py`,
`test_wrap_copilot.py`, and `test_wrap_bridge.py` to read with
`encoding="utf-8"`
- Add `test_inject_rtk_handles_utf8_content` verifying that existing
hint files with smart quotes and em dashes survive RTK injection without
crashing
## Testing
- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [ ] Manual testing performed
### Test Output
```text
$ python -m pytest tests/test_cli/test_wrap_hintfile_agents.py tests/test_cli/test_wrap_copilot.py tests/test_cli/test_wrap_bridge.py -v
47 passed in 1.28s
```
## Real Behavior Proof
- Environment: Windows 11 China (GBK locale), Python 3.11, headroom main
(f03e77b)
- Exact command / steps: python -m pytest
tests/test_cli/test_wrap_hintfile_agents.py -v (on GBK Windows)
- Observed result: Before fix,
test_prepare_only_injects_rtk_into_hintfile fails with
UnicodeDecodeError 'gbk' at position 283 (the em dash in RTK block).
After fix, all 12 hintfile tests pass including new UTF-8 round-trip
test.
- Not tested: no manual `headroom wrap copilot` run against a real
Copilot installation

## Additional Notes
This is the same class of bug reported in #733 (GBK config.toml
corruption). This PR fixes the `wrap.py` call sites; other modules
(`learn/analyzer.py`, `install/providers.py`) have the same pattern and
could benefit from the same treatment in a follow-up.

Add host-managed OpenClaw wrap and unwrap flows to the Docker-native wrappers so the installed headroom script can configure the OpenClaw plugin on the host while keeping Headroom itself in Docker. Reuse hidden prepare-only hooks for OpenClaw config payloads, preserve existing plugin metadata on unwrap, and update the Docker-native and integration docs to reflect the supported flow.

Add system-native install scripts and host wrappers for running Headroom from Docker while keeping wrapped tools on the host. Document the Docker-native path, add a complete CLI reference with help output and parity details, and add support for root help/version aliases and proxy env-based binding behavior.
