* fix(ci)!: verify exact conformance fixture records
BREAKING CHANGE: Regenerate unversioned conformance manifests with npm run build:fixtures. Schema version 2 separates exact string markers from intentional fragments and rejects the ambiguous strings field.
* test(conformance): wait out a cold verifier instead of treating SIGTERM as rejection
The compiler-produced complete/REA_C_ENTRY run was killed by its 10s
execFile timeout on the loaded source-test runner, with empty stderr and
SIGTERM. The stricter record checks already passed locally and for the
other compiler-produced cases. Assert the process status and give that
cold run room inside the test budget.
* fix(ci): preserve carriage returns in nm symbol records
nm -j terminates each name with LF. A carriage return before that LF is
part of the symbol. Splitting on CR LF dropped it, so a renamed symbol
ending in CR matched the name without it.
* test(ci): supervise conformance verifier subprocesses
