feat(cua-driver): add bounded feature telemetry

[f-trycua]

Summary

• classify reviewed finite CLI operations and MCP configuration client kinds before worker handoff
• add fixed operation categories for compound page calls
• capture cross-platform cursor outcome categories immediately before session cleanup
• expose an observed flag so missing cursor state is not interpreted as disabled
• isolate GUI behavior harnesses from live telemetry by default while retaining explicit opt-in
• document the expanded content-free telemetry contract

Validation

• cargo test -p cua-driver-core --locked
• cargo test -p cua-driver --bin cua-driver --locked
• cargo test -p cursor-overlay --locked
• cargo test -p platform-macos cursor --locked
• cargo check -p cua-driver-testkit --locked
• cargo check across core, cursor overlay, all platform crates, and the binary
• npx tsx scripts/docs-generators/runner.ts --library cua-driver --check
• telemetry inspect for CLI, tool-completion, and session-end schemas
