* refactor: remove TypeScript 6 from plugin runtime and tooling
Keep source plugin loading on Jiti and native module transforms, move development analysis and declaration builds to TypeScript 7, and preserve captured loader and input ownership contracts. Scaffolds compile to the same entry path without shipping a compiler in production.
* refactor: use native checker for restart preflight detection
* fix: keep test-directory docs out of native helper scans
* fix: preserve native compiler tooling across CI runtimes
Keep compiler-backed tests on the supported Node transport, preserve declared Windows aliases and partial-source analysis, and bind relocated SDK reports to their installed compiler. Retain strict package input admission and the existing fixture assertions.
* test: compare messaging guard diagnostics without sorting
* fix: bound native tooling memory and preserve bootstrap loading
* fix: bound native declaration builds with tsdown scheduling
* fix: retire compiler-only helpers from installed packages
* test: migrate routing import scan to native parser
* test(ui): wait for recovered model catalog receipt
