- Added scripts/fix-dts-extensions.test.ts to the test:scripts npm script.
- Included the .d.ts extension rewrite test in the CI workspace test suite.
- Updated repoScriptTests list in scripts/ci-test-ts.ts to ensure consistent tracking.

+- Added `classifyJsonPrefix`, a strict RFC 8259 streaming-buffer classifier (`"complete" | "prefix" | "invalid"`). Providers use it to disambiguate identifierless streaming tool-call deltas: a `{`-prefixed chunk only advances to a sibling call when the current argument buffer cannot absorb it.
