the spell owns its state, and a malformed file is refused, not a crash

- the spell owns its lifecycle state: the in-flight cast, the local cancel, the cooldowns and the spell-modifier tables live in one module (2328)
- a malformed MPQ, DBC, M2 or WDT file is refused instead of crashing the client, nine read sites bounded
- a test that needs the install or the addon corpus fails instead of skipping when the data is there; the Bagnon render suite runs again (2329)
- the dev crash injector is armed on every platform, and no instrument writes a path relative to the working directory
