fix: add F1-F12 symbol keys to Rl:: (phase 6 settings-toggle used :f2)

Phase 6's settings panel toggles on F2, but Rl::resolve_key's SYMBOL_KEYS map
only had letters/digits/a few named keys — :f2 raised ArgumentError and crashed
the loop at frame 1. Added f1..f12 (raylib keycodes 290-301) to the map.
The KEY_F* constants aren't all exposed to mruby, so the int values are used.

(orchestrator fix — unblocked the final end-to-end verification.)
