v26.2.0

• Add /gs ping so players can view their ping and compensation status.
• Add /gs toggle so players can opt their own compensation on or off.

• Remove unused knockback/velocity code paths and tidy PlayerData.

• Add /gs status and tab completion.
• Add Modrinth publish workflow that refuses to publish without a changelog.
