Distilled from PR #702 (fixes#697):
- install.ps1: replace the try/catch that swallowed `codebase-memory-mcp
install` failures with a $LASTEXITCODE check that reports the exit
code and fails the installer, instead of silently leaving no coding
agent configured.
- README: document Unblock-File for the Mark-of-the-Web restriction
that blocks the downloaded install.ps1, plus the execution-policy
escape hatch.
- cbm_exec_no_shell (Windows): switch from _spawnvp, whose CRT does not
quote arguments containing spaces (the taskkill filter "IMAGENAME eq
codebase-memory-mcp.exe" arrived as three bare tokens), to
CreateProcessW over a two-pass MSVC-convention quoted command line
(cbm_build_cmdline, exposed for tests via compat_fs_internal.h).
- UTF-8-correct widening: the quoted command line is assembled in UTF-8
bytes and converted once via cbm_utf8_to_wide, so non-ASCII arguments
(e.g. a non-ASCII %USERPROFILE%) survive intact instead of being
byte-widened as Latin-1 mojibake.
- tests: regression guard for the #697 taskkill filter, MSVC quoting
edge cases (empty arg, embedded quote, trailing backslashes), UTF-8
widening guards (2-byte sequence with explicit code points; mixed
2-/3-byte round-trip via cbm_utf8_to_wide), and live CreateProcessW
spawn tests. All Windows-only, exercised by the Windows CI leg.
