* fix(windows): resolve daemon startup failures and Git Bash compatibility
Three root causes behind 27 open Windows issues:
1. Path::canonicalize() returns \\?\ prefixed paths on Windows that
Node.js cannot parse, preventing daemon startup. Strip the prefix
before passing to Node. (fixes#522, #390, #56, #25, #37, #89)
2. Git Bash/MSYS2 translates Unix-style paths and resolves node to
a shell wrapper script. Use node.exe explicitly and set
MSYS_NO_PATHCONV/MSYS2_ARG_CONV_EXCL to prevent argument mangling.
(fixes#148, #108, #171)
3. postinstall fixWindowsShims() hardcoded x64 arch and did not verify
the native binary exists before rewriting shims. Now detects arch
dynamically and validates the binary path. (fixes#262)
Also:
- Error messages now show TCP port on Windows instead of Unix socket path
- Windows CI expanded to test full daemon lifecycle (open, snapshot, close)
* fix(windows): strip \\?\ prefix in auth-cli path (fixes#579)
Same canonicalize() issue as the daemon spawn path, but in
run_auth_cli() which passes the script path to Node.js.
