chore(release): v0.19.13 + fix sync-checksums.sh cross-target contamination

Discovered chasing down the last remaining CodeQL Swift failure on main.

Problem chain:
1. Package.swift had stale checksums that didn't match v0.19.12 binaries
2. release.yml has a "Sync Package.swift checksums" step that calls
   scripts/sync-checksums.sh, but it was silently no-op'ing forever
3. Even when I forced it to run, it was putting the WRONG hash on each
   target (RACommons got LlamaCPP's hash, LlamaCPP got RACommons', etc.)

Root causes:
- The outer glob `RACommons-v*.zip` doesn't match the post-v0.19.0 naming
  `RACommons-ios-v*.zip`. Fixed to `RACommons-ios-v*.zip`.
- sync-checksums.sh internal mapping used old prefixes too. Updated.
- sync-checksums.sh regex for update_checksum_line used non-greedy `.*?`
  DOTALL matching `name: "X"...checksum:`. Package.swift has two entries
  per binary (local-mode with `path:` and no checksum, remote-mode with
  `url:`/`checksum:`). The regex hit the local entry first, then scanned
  forward to the NEXT `checksum:` in the file — which belongs to a
  DIFFERENT target. Result: cross-target checksum contamination.
  Fix: require `url:` between name and checksum to skip local-mode entries.

Also updates Package.swift with v0.19.12's actual binary checksums so
main has a known-good reference. The follow-up PR after v0.19.13 release
will replace these with v0.19.13's checksums (since builds aren't fully
deterministic — this is a known wart, documented in release.yml).

Bumps to 0.19.13.
