0.2.5-dev: community round 30 and follow-ups

- Stock: fixed trait gifts (缪尔赛思 / 变形者集群 变形同构体, 耶拉 不融冰, 蜜蜡 / 卡涅利安 迅捷作战粮, 诗怀雅 盟约之币) still occupy stock but are granted past the cap; an operator card already shown in the shop or a reward can be taken after the pool runs out and overdraws (GitHub #498, the owner's decision); item buys and item rewards keep the stock check. 洛洛 / 焰尾 sub-pools use the measured weights (PR #497 by @2321Robin; the occupancy idea of PR #496 by @2321Robin re-implemented differently).
- Boss pairs are drawn at random once per match and fixed to battle start; the Hidden Core reuses them; a leaver does not split a full pair (the owner's decision).
- 阿戈尔 in 联防 no longer re-applies the opening devour HP loss or a false revive; Touch's team medic stays for the match after its holder leaves (owner-approved, official lifetime unverified).
- Auto-skill ranges: 司霆惊蛰 S2, 斩业星熊 S3 against air, 予愿安洁莉娜 S3; 自在's post-rebirth invulnerability is also untargetable (#510); Horn / Clementia / catapult / 忍冬 first hit (PR #502 by @Xinglan233); 不融冰 / tear gas trigger on real damage.
- Bond layer-up sound in round start / draft / prep / battle (#482): one channel, a new cue replaces the old, no extra cooldown; a prep update that adds layers and activates a bond plays one cue.
- Client: multi-swing fix (#506), refresh single-flight (PR #507 by @robll-v1), LP tower keeps the settled value with a −N tick (PR #504 by @robll-v1), export with only 潜能 / 练度 changes (PR #503 by @Xinglan233), spectator rosters list DIY members (PR #505 by @Xinglan233), banned members beside bond tooltips (PR #494 by @YuriRestia), recovery action above the away overlay (PR #511 by @RainoutOvO), the /dev/sim-check.html consistency page (PR #492 by @Cloudnyco), Korean (PR #490 by @D-Roote) and English Victoria wording (PR #499 by @YuriRestia).
- golden: 45 of 287 scenarios move against 0.2.4 (roster 17, bonds 3, fields 6, matches 17, standins 2), each attributed in docs/history/0.2.5.md §30.9 / §30.16.
