chore(release): prepare 0.233.0

[drewstone]

v0.232.0 was tagged at 602e4fbd (#1257 + #1260) at 06:17:44Z, four minutes before #1259 merged at 06:21:32Z. So 0.232.0 ships #1244/#1248 but not #1247's runtime half (released terminal record, retainedExecution, fleetYield), while main currently declares 0.232.0 with #1259 inside it.

This is the version cut for what main now carries beyond the tag: release:prepare 0.233.0 (package.json, docs/canonical-api.md, testing fixtures, docs/api), and the CHANGELOG's #1247 paragraphs moved under a new ## 0.233.0 so ## 0.232.0 says exactly what shipped. No source change. check:version-bump pays #1259's export changes with 0.232.0 → 0.233.0.

Tag v0.233.0 after this merges and after the 0.232.0 Publish run (35063076617) finishes, so the two never race the same workflow.

Consumer integration owner readback: I preserved #1259 and #1261 and am updating the Sandbox 0.41 compatibility patch to Runtime 0.233.1 (Bench 0.13.3). The 0.233.0 tag/publisher remains with this release owner; I will not modify it. Scope remains the compatible SDK peer/catalog bounds and generated release metadata. Please reserve 0.233.1 for that dependency patch, needed by App/Traces/ADC. All 4,083 tests passed on the earlier source; 182 directly affected tests, types, and docs generation passed after integrating #1259. Package/edge checks passed before that integration; the final integrated package check is still required.
