feedback5 WJ: 伺夜's 狼群 takes its official 战术点形态 and S1 领袖的呼唤 acts by the pack's state (PRTS 狼群领袖 / S1 备注)

The fatal hit on the last 狼影, or a 撤退 while 伺夜 stands, no longer kills the pack. It enters its 战术点形态, the
remake's knocked-out piece: off the fight (no block, no attack, not targetable), kept, its tile reserved, 0 狼影. After
the 狼影 recovery time it comes back on its tile at full HP with 1 狼影 and a fresh 狼影 cycle. That time is the token
talent's interval, read from the data: 25 s on both chess. Until now it came back after the token's 10 s redeploy time
with 2 狼影.

Both packs share this (tokens.js installWolfTacticalPoint): the prep-placed 狼群 piece and the 伺夜 kit's own pack.
- A return timer carries the form's seq and a return cancels it, so a stale timer never revives the pack early.
- When 伺夜 leaves, a standing pack still leaves with him ('expired', no form). A pack in its form ends it with no
  return; his redeploy brings a fresh pack.

S1 casts when ready while the pack is on the field in either form, and always pays +cost DP:
① in its 战术点形态 the pack comes back at once with 1 狼影 and a fresh cycle;
② below the cap, +1 狼影, the pack's own cycle untouched;
③ at the cap, the pack's HP is reset to max.
S2 still needs a standing pack: its 备注 says nothing of the form [ASSUMED]. A held S2 gift stays on the pack through
the form [ASSUMED].

fx: the kit's pack keeps 'summon' / 'revive', the piece keeps 'wolfShadow' / 'wolfShadowLost'. Entering the form shows
'wolfShadowLost' with count 0. No new kinds, no client change. Data unchanged.

Tests:
- kits_alt_t3, new: 3_19 战术点形态 (both chess × both packs), S1 ①②③ with the stale-timer guard, 撤退 / 伺夜 leaving.
- kits_alt_t3, rewritten: the S1 no-pack test, and the S2 auto-cast test (no cast in the form, a cast once the pack is
  back).
- kits_t3 3_19 wolf pack and tokens_devices 狼群 board piece: the form, then a return with 1 狼影.

Golden (each fields 伺夜 with his pack knocked out at its last 狼影 while he stands: 25 s out and 1 狼影 instead of
10 s and 2):
- roster-007 and roster-009: the fights change.
- roster-028 (elite S1): S1 brings the pack back at once.
- roster-026 and roster-040: 伺夜 falls before the old return; only the new 'wolfShadowLost' fx moves.
- bond-siracusaShip-high.
- matches solo-NORMAL-1, coop2-NORMAL-3, coop3-ABYSS-5, coop2-NORMAL-8-serverrun: the bots field 伺夜.
