* fix(#1693): don't double-quote $CLAUDE_PROJECT_DIR-anchored hook paths on Windows

The installer's #2979 legacy-node rewrite ran every managed node hook path
through JSON.stringify on Windows. For local installs the path already carries
a "$CLAUDE_PROJECT_DIR"-anchored quoted prefix, so stringifying produced
"\"$CLAUDE_PROJECT_DIR\"/...". Node then received an argument starting with a
literal " , treated it as relative, and failed MODULE_NOT_FOUND — breaking
every node managed hook at once (a self-locking PreToolUse-guard deadlock).

projectLegacySettingsHookCommand now emits an already-anchored token verbatim
and only JSON.stringify-quotes bare absolute paths (which may contain spaces).
Scoped to win32 so non-Windows token-shape behavior is unchanged.
