Chinesezjc 2a9a917853 fix(code-runtime-python): drop a late binding resolution before snapshotting it
`sendReply` already refuses to write after the run settled, but only after
`snapshotJsonValue` walked and copied the resolution. Binding resolution carries
no seam-level byte cap, so a binding resolving a wide value after `maxWallMs`,
an abort, or dispose settled the run spent host heap building a frame that was
then discarded. The check moves ahead of the snapshot.

Also in this change:

- `readProcessStart` moved after `messageOf`. Inserting it between `messageOf`'s
  JSDoc and its body left that function undocumented and the orphaned block
  reading as a second doc for the reader; `verify-export-jsdoc` does not catch it
  because `messageOf` is not exported.
- The README pair adds the disposed-runtime rejection to `run()`'s public
  contract, which `src/index.ts` has enforced all along.
- Known Limitations records three deferred constraints that until now existed
  only in review discussion: the combined log-and-value peak the load gate does
  not model, the host-side per-member expansion of a wide binding reply (owned by
  `packages/core/session`, and shared with the worker-thread backend), and the
  absence of fd-3 backpressure for concurrent replies.
- The Agent Note's same-group section records the teardown identity guard and its
  two rulings, including why an ABSENT start-time reading proceeds rather than
  withholding the signal, and that reading it as a mismatch is what turned the
  three same-group heartbeat cases red on Linux.
