Add Charity and Revival resource practice

Expand the internal introduction to eleven lessons and nine independent Basic exercises. Charity shows the ordinary top-up to two spice and prevents duplicate claims. Revival lets Atreides, Emperor and Fremen return ordinary forces in batches and revive an eligible leader using the same spice balance. Reuse production charity and revival calculations; only narrow the leader-options TypeScript signature, with no live rules or AI strategy changes.

Version 5 practice saves retain all earlier lesson identities and accepted choices. Replay a bounded, validated history to reconstruct spice, Tanks, reserves, leader custody and turn allowances. Cover first-cycle, surviving-leader and repeat-death rosters, cumulative free allowances, paid returns, the three-force cap, separate leader allowance and unaffordable choices. Seven new tests compare real engine actions, immutable inputs, migration and impossible-save rejection.

Independent review found no material issues. Types, lint, 4941 offline tests and production build passed on stable final source. Browser checks confirm previous alliance migration, keyboard Charity, shared revival spending, refreshed force/leader outcomes, roster restrictions, faction free rates, cap rejection and leader inspection. At390px all observed new controls fit, with 44px or taller targets. Screenshot capture remains unavailable; DOM bounds are narrower evidence. The full curriculum, faction/expansion teaching and rules/publication gates remain incomplete.

Reused the running server. A stale development import for the newly-created file cleared through import-graph invalidation and reload without restarting. All 1337 rooms, 2805 seats and existing recovery, entry, handover, delegation and migration rows remain unchanged. SQLite integrity and foreign keys pass. No database migration/reset, automation, usage check or AI calibration. HTTP/auth/persistence source is unchanged; the required offline suite includes recovery checks and no broad HTTP suite was rerun.
