fix: correct community-reported combat and strategy draft behavior

Guard lethal stuns against a replacement deployment; keep bard auras running
through stun; require an active Aegir bond for Clementia's strategy; allow
Compass SP to bypass recovery locks; and refresh Hidden Core gun mitigation
against current gun/spring companions. Set multiplayer strategy picks to 50s
and describe renderer fallback without diagnosing unsupported hardware.

Golden moves (full 285-scenario regeneration):
- roster-008: inactive Aegir no longer gains 18 strategy layers.
- boss-boss_4-solo: bard regeneration continues through stun.
- hidden-boss_9-pair: mitigation covers first hits/current companions.
- standin-07: hammer stun cannot follow an immediate revival deployment.
No ending-reason changes. Sources and report-by-report findings: DESIGN 28.25.
