feedback5 O13: 假日威龙陈's slime follows the client data (her attack range, per source, DEF as a final addition) and the water TAG is one flag; 莱伊's S2 bullet recovery takes HUN-X's extra on an empty magazine

- op-chen2.js: the S2 / S3 slime (projectile_chr_chen2_s2 / _s3: fired by each attack, sitting on her in her direction,
  5 s, every 0.2 s chen2_slime 0.25 s on the ground enemies of its range, ignoring 无法选择) now covers the tiles of her
  attack range at each attack instead of the struck enemies' tiles; one effect per 假日威龙陈 (independentCharacterSource);
  the DEF cut compensated for the target's DEF multipliers (FINAL_ADDITION). RPR-Y stage 3's water TAG is the level's one
  flag (chen2_e_003_t[map_tag]: set at her skill's start, cleared at its end or her exit). S2's attacks stay skill attacks.
- op-ray.js: the 沙地兽's recovered bullets go through ray_tr_add (≤ its counter of 8, HUN-X's extra_add first when she is
  empty, ≤ her magazine); kit headers cite the client templates (also op-ascln.js).
- Tests: op_chen2.test.js slime test rewritten (her range, stealthed walkers, the final-addition DEF, two sources).
- Golden: only diy moved — diy-049 / diy-050 (假日威龙陈's slime); every other scenario and family unchanged.
