feat: improve remote browser tree routing

- Allow remote host aliases passed via --browser to fan out for read-only
  multi-browser SDK paths while preserving strict routing for mutating commands.
- Add remote host grouping and scoped profile labels to tabs tree output so
  global views avoid repeated host prefixes.
- Carry browser family metadata through remote targets, tabs, and groups and
  style tree browser labels by family.
- Split CLI rendering helpers into a typed rendering package with dedicated
  common, label, tabs-tree, and windows-tree modules.
- Bump browser-cli and extension versions to 0.15.5.
- Cover the new routing and rendering behavior with unit and CLI tests.
