release symbols: dump_syms logged a CFI error and still stored the symbol file #364

Two Native desktop - macOS arm64 runs on main logged an error from the symbol dump and then stored the archive as if it were complete:

• 2026-11-06, run 42306937978: [ERROR] CFI: CfiError { kind: BadDebugInfo, source: Some(UnknownVersion(0)) }
• 2026-11-07, run 42332978679: CFI: CfiError { kind: BadDebugInfo, source: Some(OffsetOutOfBounds(3005218816)) }

The three later arm64 logs that were checked (2026-11-09 and 2026-11-13) have no such line.

To do: find out whether the stored .sym file lacks unwind (CFI) records when this happens, and make scripts/dump-symbols.ts fail, or verify the output, when dump_syms reports an error. Whether a release was built from an affected run was not checked.

Found while diagnosing #359.
