fix(ci): correctly skip code CI for docs-only PRs (#6800)

dorny/paths-filter treats exclusion-only patterns as matching every
non-excluded path under the default "some" quantifier, so docs-only
PRs still set code=true. Add an explicit "**" include and use
predicate-quantifier: every in tests, type-checker, and linter.

Also gate Vulnerability Scan the same way on pull_request while
keeping schedule and main push runs unconditional.
