v6.1.1

Patch — one real fix + a full documentation correction pass.

Fixed

• chart.recorder() no longer silently drops emit recorders. The fluent
  chart.recorder(rec).run() sugar detected only the scope + flow channels, so a
  recorder implementing only onEmit got zero events with no error. It now routes
  through the executor's combined-attach logic (scope/flow/emit detected uniformly,
  deduped — no double-attach).

Docs

• Audited + corrected every hand-written doc and JSDoc @example against the
  current code (recorder family especially: v5 *Store classes vs the deprecated
  bases, executor method names, builder arg forms, resume() semantics).
