M4 partial — Search shipped, browse UI live on the Pi

Sidecar gains the 'search' op via rustypipe's
query().search::<VideoItem,_>() — returns id, title, channel, duration,
thumbnails, view_count. Default limit 25.

Addon root directory is no longer a placeholder notification:
- 'Search' entry → ?action=search → keyboard input → result list →
  tap a result to play (each result is a play-action plugin URL).
- 'Play by URL' entry → ?action=play_by_url → keyboard input → PlayMedia.
- ?action=search also accepts inline 'q=…' so JSON-RPC clients can
  drive search without going through the on-TV keyboard (useful for
  share-to-TV from phone + tests).
- Result labels formatted as 'Title  ·  Channel  ·  Duration  ·  Views',
  with thumbnail + Kodi InfoLabels for richer skin views.

Verified via Files.GetDirectory JSON-RPC: 19 well-formatted LTT results
returned for query 'linus tech tips'.

Pending M4: channel browse, playlist browse, pagination, search history.
Addon version 0.0.6.
