Chrome bridge gains roster change notifications, retained tool args and permission categories

You'll notice
Useful2 Signal0
Chrome & Browser

The Chrome bridge now refreshes the extension list on connect or disconnect and keeps pending tool arguments.

What

The bridge context can now tell the UI when the set of connected extensions changes, keeps the arguments of pending tool calls, and accepts a category on incoming permission requests.

Details
  • New onPeerRosterChanged callback fires on pair, peer connect, peer disconnect and teardown, so the extension list can be refreshed.
  • Pending tool calls now retain their args instead of discarding them.
  • Permission requests carry a category validated against ^category[0-9a-z_]{1,32}$; a value that does not match is dropped rather than passed through.
Evidence

onPeerRosterChanged

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
