feat: mount trace CLI; library-only deps via go.work at v0.1.0

- Mount the trace command tree under 'hawk trace ...' (cmd/trace.go) via
  tracecli.NewRootCmd(); remove standalone cmd/{inspect,sight,tok,yaad}.go
  and the sessioncapture bridge (superseded).
- Normalize all GrayCodeAI requires to v0.1.0; go work sync settles go.mod/
  go.sum/go.work.sum to the workspace-consistent state.
- external/ submodule pointers bumped to each sibling's current main.
