Update @github/copilot to 1.0.63 (#1686)

* Update @github/copilot to 1.0.63

- Updated nodejs and test harness dependencies
- Re-ran code generators
- Formatted generated code

* Fix Rust E2E test for new ignore_whitespace field on WorkspacesDiffRequest

The 1.0.63 type regeneration added an optional ignore_whitespace field to
the generated WorkspacesDiffRequest struct. The explicit struct literal in
rpc_workspace_checkpoints.rs failed to compile (E0063: missing field), which
broke clippy on ubuntu and cargo test on macos/windows. Add ..Default::default()
to the literal, matching the existing pattern in rpc_session_state.rs.
