fix(observer): hook-resolver — Windows backslash path support

Code-review followup. TOOL_SCRIPT_RE didn't include \ in delimiter
char class — Windows-native commands like `node tools\foo.mjs` fell
through to inline:<sha> fallback. Added \ to char class + inner
[\/\] alternation, normalize match to forward-slash.
