Two fixes for the local terminal backend on Windows (Git Bash):
1. `_drain()` in base.py: `select.select()` only works on sockets on
Windows, not pipe file descriptors. On Windows, use blocking
`os.read()` in the daemon thread instead. EOF arrives promptly
when bash exits, so this is safe.
2. `_run_bash()` in local.py: When `self.cwd` is updated from `pwd`
output, it contains Git Bash-style paths (`/c/Users/...`).
`subprocess.Popen(cwd=...)` needs a native Windows path
(`C:\Users\...`). Added a conversion before Popen.
Without these fixes, all terminal() calls on Windows return empty
output (exit code 126), and cwd tracking breaks.
Tested on Windows 11 with Git for Windows + Python 3.13.
Fixes#14638
On Windows, services and terminals default to cp1252 encoding. The CLI
uses box-drawing characters (┌│├└─) in banners, doctor output, and
status displays. When print() tries to encode these under cp1252, an
unhandled UnicodeEncodeError crashes the gateway on startup.
This fix adds early UTF-8 enforcement in hermes_cli/__init__.py:
- Sets PYTHONUTF8=1 and PYTHONIOENCODING=utf-8
- Re-opens stdout/stderr with UTF-8 encoding if not already UTF-8
Runs at import time so it protects all CLI subcommands. No effect on
Unix (gated on sys.platform == "win32"). Backwards-compatible: on
systems already using UTF-8, the function is a no-op.
Fixes#10956
