Describe Brawl as unarmed non-lethal combat

[RANGROO]

Summary

• describe Brawl consistently as an agreed, bare-fisted, non-lethal fight in English and German
• keep both the player and nearby NPCs available as valid brawl targets
• distinguish Brawl from lethal Attack without exposing internal runtime mechanics
• update the built-in action seed and migration 20260825001
• migrate customized Brawl rows only when both their description and parameter schema still match the old defaults

Companion game-plugin PR

• CHIM draft: https://github.com/Dwemer-Dynamics/CHIM/pull/172

Validation

• php -l passed for all four changed PHP files
• php vendor/bin/phpunit tests/CoreRequestStabilityTest.php — 7 tests, 13 assertions passed
• focused action-schema probe confirmed Brawl accepts the player or a nearby NPC
• both migration statements executed successfully inside a PostgreSQL transaction and were rolled back
• core_action_seed.sql imported 53 rows successfully inside a PostgreSQL transaction and was rolled back

Full-suite baseline limits

The full Windows PHPUnit run reached 268 tests but is not clean on this host: 16 environment/harness errors (PostgreSQL setup and missing Zip extension), 2 unrelated existing assertion failures, and 1 missing-test-class warning. No changed-path failure was observed.

• not deployed
