chore(release): prepare 3.1.13

[ifBars]

Summary

• bump the S1API project package version from 3.1.12 to 3.1.13
• bump the MelonLoader assembly metadata version from 3.1.12 to 3.1.13
• prepare the immutable releases/3.1.13 branch for tag-driven publication

Validation

• Mono solution build: zero warnings/errors
• Mono tests: 556/556 passed
• IL2CPP solution build: zero warnings/errors
• IL2CPP tests: 545/545 passed
• DocFX: zero errors; four pre-existing local unresolved dependency warnings

Compatibility

• Public/protected API inventory: no symbol changes; version metadata only
• Source, binary, behavioral, save, and network compatibility are unchanged
• Omitted/default inputs, invalid inputs, duplicate registration, builder reuse, save/load, and multiplayer behavior are unaffected by this release-only change

Release policy

After this PR merges into stable, fast-forward releases/3.1.13 to the stable merge commit and tag that exact shared commit as v3.1.13.
