ci: multi-version build matrix + multi-MC compat layer
- Parametrize build: -PmcVersion / -PapiCoordinate / -PjavaRelease / -PapiVersion;
jar name includes mc version, plugin.yml api-version parametrized
- Compat (reflection): sendBlockChanges / getClientViewDistance /
getStructureManager (Paper 1.19.3+); particle()/potionEffect() name lookup
for 1.21 renames (BLOCK_CRACK->BLOCK, REDSTONE->DUST, FIREWORKS_SPARK->
FIREWORK, JUMP->JUMP_BOOST, SLOW->SLOWNESS); drop CHERRY materials (1.20+)
- Fix Java 17 'unconditional instanceof' in JoinCommandExecutor
- capabilitiesResolution for org.bukkit:bukkit capability conflict on newer
paper-api artifacts
- .github/workflows/build.yml: matrix for 1.19.2/1.20.1 (Java 17),
1.21/1.21.11 (Java 21), 26.1.2/26.2 (Java 25) + quality gate
- Verified locally: default + 1.19.2/1.20.1/1.21/1.21.11 build; 26.x deps resolve
