Require Trace v3 version const 3, reject mixed pages/states payloads, and
align TypeScript selection optionality with the generated schema. Trace v2
on main already records hover steps, so the frozen v2 schema must accept
them instead of dropping them during reduction.

Define Trace v3 wire types and generated schemas while keeping protocol
1.1 peers compatible with 1.0. Default record start still produces Trace
v2, and only an explicit trace_version=3 request enables the new shape.

Capture user actions in the Agent Window and export a record-only
trace (pages[] + navigate/click/fill/select/press steps with target
descriptors). Adds the record overlay UI aligned with the control
overlay, and wires record start/stop/await through CLI, daemon,
protocol, and extension.
