Merge branch 'main' into bb/gui

Conflicts resolved:
- package.json / package-lock.json: drop @askjo/camofox-browser from
  root deps per main's lazy-install change (#27055); keep bb/gui's
  workspaces=["apps/*"] and @streamdown/math; regenerated lockfile.
- hermes_cli/main.py (_update_node_dependencies): combine main's
  streaming-output change (drop --silent, capture_output=False so
  postinstall progress is visible — #18840) with bb/gui's
  --workspaces=false guard so npm does not recurse into apps/*
  workspaces (those install/build on demand via _build_web_ui).
- hermes_cli/main.py (_BUILTIN_SUBCOMMANDS): add main's new
  'send' subcommand so plugin-discovery fast-path skips it.
- tests/hermes_cli/test_cmd_update.py: align with combined flag set
  (repo gets --workspaces=false, ui-tui does not, dashboard install
  + build still 3rd) and retain main's capture_output=False
  regression assertion for repo + ui-tui installs.
