Phase 6c of the go-port-cloud-run plan. Adds the third loldle variant
— guess the champion from a single ability icon (passive or Q/W/E/R).
- internal/modules/loldleability: champions.go (embed
abilities.json, 5334-line DDragon-sourced pool with
AbilityChampion + Ability types), state.go (gameState gains a
`slot` field so the same icon shows across guesses in a round),
render-free handlers.go (sendPhoto path uses
models.InputFileString with the DDragon CDN URL directly — no
binary upload), loldleability.go (Module Factory).
- Reuses internal/modules/util/chathelper and internal/champname
(same shared layer the other variants use).
- 4 commands wired: loldle_ability (public), loldle_ability_giveup
(public), loldle_ability_stats (public), loldle_ability_setmax
(private).
- 14 tests: lookup (embed shape + DDragon URL prefix + slot
coverage), state (slot round-trip + JS-wire-format decode +
streak), handlers (sendPhoto with correct URL, win, unknown
champion, duplicate, giveup with slot label, stats, setmax owner
+ non-owner).
- gocyclo cap nudged 20 -> 22 to accommodate handleAbility's
pre-flight validation branch.
