* fix(scanner): widen WASM panic recovery to cover tag/property reading
The panic recovery in gotaglib's extractMetadata was only inside
openFile(), which covers taglib.OpenStream(). Panics from f.AllTags()
and f.Properties() (e.g. readString crashes on malformed files) were
uncaught, crashing the scanner subprocess with exit status 2.
Move the recover() up to extractMetadata() so it covers the entire
tag reading lifecycle, matching the CGO taglib wrapper's approach.
Fixes#5220
* fix(scanner): use consistent log key "filePath" in panic recovery
* fix(scanner): include stack trace in WASM panic recovery log
