0.2.3: prepare follow-up fixes and client features (#407, #408, #410, #413, #431, #435, #436, #440, #444)

Add special-target activation without bypassing attack cadence, cooperative
card preferences and emotes, skill sound banks, per-operator voice choices,
text sizing, install prompts, closed-tab recovery and unanimous setup rerolls.
Retain late deployment elapsed time and resolve echo/counter pulses without
recursive hook overflow. Independent final review remains pending.

Golden: roster-016, roster-035, roster-036, roster-045;
boss-boss_1-pair, boss-boss_3-pair, boss-boss_5-pair, boss-boss_7-pair,
hidden-boss_9-pair; solo-HARD-9-boosted: Lemuen attack cadence.
diy-132: Necras extra activation targets.
coop2-NORMAL-14-standins: cooperative purchase preference and simulation fixes.
hidden-boss_10-solo: echo pulse FIFO resolution.
