Temporary draft for checking out and testing the rebased Cua Driver integration on another machine. Carries the original work by Francesco Bonacci from #10899, whose organization-owned fork does not permit our pushes.

Adds default-off Cua computer use for Codex sessions, with desktop and standalone host support. Rebased onto main, adapted the Settings and tool-capability conflicts, and fixed the Effect service conventions findings: dependency acquisition, namespace imports, structured failures with preserved causes, and documented diagnostic suppression.

Validation: 154 focused tests passed, including desktop lifecycle and telemetry unit tests; server and desktop typechecks, targeted lint, and formatting passed. Earlier rebase verification passed 372 server/contracts/packaging tests and web/contracts typechecks. Desktop unit tests used mocked native hosts and an Electron path override to avoid a download on a disk-constrained machine.

This PR is for checkout and testing, not a merge-readiness claim. Current UI screenshots and native end-to-end verification have not been refreshed after the rebase. Original integration evidence and remaining platform limitations are recorded in #10899.

Original implementation by Francesco Bonacci with Codex. Rebase and convention fixes by GPT-6 in Codex.
