Remove macos-13 (Intel) runner from CI (#388)

macos-13 was retired by GitHub in December 2025 and no longer works.
Intel-based macOS runners are being phased out entirely by GitHub,
with only expensive *-large variants remaining as alternatives.

Closes #387

+> `PUB-CACHE-HIT` and `CACHE-HIT` directly use the `cache-hit` output from `actions/cache@v5`, which is the following:
+> - `cache-hit` - A string value to indicate an exact match was found for the key.
