Module fix 

Applying the fixes that diagnostics carry (htl fix).

The shape follows what cargo fix, ESLint and Ruff settled on: a fix travels with its diagnostic and has an applicability class; only safe applies unless asked; edits that overlap within one pass are deferred to the next, which re-checks the file; passes are capped; a fix that leaves the file with an error it did not have is reverted; everything applied is reported, not only what remains. A file the parser rejects is never touched; type errors do not block (their positions are sound, and a fix may be what removes them), the revert is the guard.
