CSE Machine Plugin (#28)

* feat(cse-machine): add common-cse-machine and runner-cse-machine packages

Local checkpoint (plugins remote is upstream; fork/push when opening the PR).

- common/cse-machine: language-agnostic CSE machine protocol — channel/plugin/
  directory ids, the snapshot-message type, and the consolidated CseSnapshot
  schema (superset of the previously-duplicated copies in py-slang, js-slang and
  the frontend: includes heapObjects, isOnCallStack, isConst, currentLine)
- runner/cse-machine: abstract CseMachinePlugin that forwards a run's CseSnapshots
  over the __cse channel; per-language serialization stays in the evaluators
- both build (rollup -> cjs/mjs/d.ts) and pass jest

* feat(cse-machine): add web-cse-machine receiver plugin

Local checkpoint.

- web/cse-machine: CseMachineHostPlugin subscribes to the __cse channel and hands
  each received CseSnapshot batch to the host via receiveSnapshots. Transport only,
  no UI deps — the adapter + Konva visualizer stay in the frontend for now
  (deferred extraction), so this plugin is small and language-agnostic.
- re-exports the common-cse-machine protocol types for host convenience.
