fix(watcher): normalize package names (pep503) during op verification

Previously, the watcher falsely identified our own FFI installs as 'External Culprits' due to differences in name normalization (e.g. FFI reported 'mkdocs-minify-plugin' while the disk wrote 'mkdocs_minify_plugin').

Injected a regex normalizer to ensure hyphens, underscores, and dots are uniformly matched, preventing redundant cache patches.
