Add opt-in browser tools for desktop tabs

* Add opt-in browser tools for desktop tabs

Adds the daemon opt-in, desktop tab routing, MCP tools, and real browser automation surfaces for Paseo desktop browser tabs.

* Fix browser tools CI expectations

* Address browser tools review findings

* Restrict browser file automation paths

* Fix browser upload test on Windows

* Harden browser navigation inputs

* Make browser tools create usable tabs

* Update browser MCP empty-state test

* Fail browser tab creation when registration times out

* Fix browser screenshots for agents

* Hide disabled browser tools from agents

* Address browser tools architecture review

* Replace browser tools review tests

* Wrap browser tab registration errors

* Mock Expo Router in app unit tests

* Handle invalid browser automation requests

* Return browser failure on desktop disconnect

* Update browser disconnect websocket test

* Relax browser timeout polling test

* Handle invalid browser responses

* Return browser failure when send fails

* Remove local diagnostics and fixture paths

* Fix dev service home fallback

* Use worktree home for dev services

* Use managed daemon in desktop dev

* fix(browser): keep agent tabs addressable

Track agent-active browser targets separately from human-focused tabs and keep resident webviews alive for automation. Browser tool visibility now comes from registration while the broker reports disabled execution.

* refactor(browser): register tools through catalog

Move browser tool registration onto the shared Paseo tool catalog so the MCP server remains only the transport adapter.

* fix(settings): translate browser tools host error
