fix(scan): run deep probe/scraper in MAIN world; reject route-template "manifests"

The video-detection pipeline was finding nothing on pages that have a bare
<video> element. Two root causes:

1. world: 'MAIN' placement. The deep probe + scraper are injected with
   chrome.scripting.executeScript. Their code (and its own comments) requires
   the MAIN world to see page globals — window.Hls, per-<video> Hls instances,
   video._goon_hls_manifest, and window.__goon_plugin_data (written by the
   main-world interceptors). The calls were missing it, so every main-world
   strategy (A/A2/E/H) found 0. It was also briefly placed inside `target`,
   which chrome.scripting rejects ("Unexpected property: 'world'"); `world` is
   a sibling of `target` on ScriptInjection. Restore it as a sibling of target.

2. fake "manifest" classification. Strategy H was reporting 10 nav links /
   server-side route TEMPLATES as manifests — e.g. /playlists/,
   /playlists/liked/, /playlist/%1%/video/%2%/, /members/%ID%/playlists/ —
   because the old /playlist|/manifest substring check matches nav menus and
   leaves %1%/%ID%/%DIR% template placeholders intact. Those then became the
   stored "video" entries, drowning out the real element.

   isManifestUrl and isValidManifestUrl now reject:
     - dynamic route templates (%NAME% or {name} tokens), using a negative
       lookahead so genuine %-encoded tokens like %2B/%2F are preserved
       (the invariant the codebase explicitly protects),
     - plural collection paths (/playlists, /manifests),
     - trailing-slash directory listings.

   The 'World: ISOLATED' probe log was also misleading (typeof chrome is not a
   world discriminator — the probe provably runs in MAIN); replaced it.

Adds a regression test (hls_qa) reproducing thisvid's pageContext.langUrls
scenario: all 10 templates are rejected while a real .m3u8 carrying a %2B token
is still detected. 90/90 tests pass; 0 lint errors; build OK.
