Playtest #3 fixes: lost models, picking, live LP, temp overflow, 蕾缪安 S3, 回环射手, FX, detail card, spinners

- #1 lost operator models: the Spine store no longer hands out a skeleton whose unload is in flight
  (PIXI.Assets.unload is async); eviction runs 1 s after a release and the empty-scene budget only after 3 s
- #7 picking: one shared rule (render/pick.js, pixel probe where bodies overlap) for prep/battle clicks,
  hover, the enemy pen and equipment drops; the drag ghost stands on its drop tile; hover probes capped
  at one per frame
- #2 the top-bar LP drops live as the own battle's enemies enter the blue gate (−N, 联防中), teammates'
  pending LP in the team panel
- #3 temp overflow pieces that arrive after a prep deadline survive through the next prep (tempDue);
  temp-row warning and ready-button reason
- #4 蕾缪安 S3: locks every 0.5 s, then one shell every 0.3 s in lock order (PRTS notes), bombardShell fx
- #5 回环射手: real boomerang (out 15, back 3.75 tiles/s, attack only when every boomerang is caught)
- #6 visible projectiles, muzzle flashes, slashes, skill bursts and auras at unchanged frame cost
- #8 特质 right under the detail card header, with its official type icon
- #9 no spinning busy cursors / spinners next to texts; game data warmed before the match
- docs, recordings and tests updated (2414 unit tests, all browser suites green)

+/**
+ * Projectile visuals per b.ev 'atk' projKind (sim: none | arrow | bolt | bomb | lob | orb | drone | enemy | boomerang;
+ * chain / chainHeal / beam are beams). Drawn by render/fx.js:
+ *   look   tracer (bullet streak + muzzle flash) | orb (glowing ball, particle trail) | shell (lobbed on an arc with a
+ *          ground shadow, smoke trail) | dart (small fast bolt) | boomerang (spins to the target and back to the thrower)
+ *   speed  tiles per game second — a copy of the sim's PROJECTILE_SPEEDS (server/sim/constants.js; `back` of the
+ *          boomerang = BOOMERANG_RETURN_SPEED, PRTS 跃跃: out 15, back 3.75). fx.js prefers the sim's own values, loaded
+ *          from /sim/constants.js, so the visual flight ends with the sim's hit; this copy stands in until then (and in
+ *          Node). test/render/fxproj.test.js keeps the two equal.
+ *   sizes  in tiles (× the camera's px per tile at the shot): `len` trail length, `width` trail thickness, `head` glow
+ *          diameter; `arc` peak height of a lob over a 3-tile throw (scales with the range)
+ *   colours `tint` hot core, `glow` halo, `trail` trail particles, `muzzle` flash at the shooter
+ *   hit    arrival burst (fx.js _impact): spark | arts | heal | boom | splash | zap | enemy
