The scanner banned as any, as {, as unknown as, non-null assertions and
ts-ignore, but said nothing about `as SomeNamedType` — so a new cast over
CDP or JSON data could be added and CI would stay green, which is the exact
regression the refactor exists to prevent. It also could not see a cast
whose target type sits on the following line.
Adds named-cast, function-cast and trailing-cast. All six surviving
assertions in src/ are now visible to the scanner and individually
exempted with a stated reason, so the allowlist is the complete inventory.

A clean tsc does not prove the absence of casts. This scans src/ for
as any, ts-ignore, non-null assertions, inline object casts, and double
casts, wired into a new npm run check that CI runs as a single step.
The escape hatch is an external allowlist module rather than an inline
comment marker: comments are not used in this codebase, and an entry
carries a count, so adding a new cast to an already-exempted file still
fails until someone raises a number that shows up in the diff. Exactly
one exemption is needed today, for the dynamic sharp import.
scripts/ was gitignored wholesale, so the two new files are un-ignored
individually and everything else dropped there stays ignored.
