feat(ai): import & analyze Windows crash dumps (.dmp) — 0.41.0

Games page gains an "Import crash dump…" button (shown when an AI provider
is configured) that parses a Proton/Wine minidump and explains it via the
opt-in AI assistant. New stdlib core/minidump.py reads the MDMP streams
(crash reason, faulting module, OS/CPU, module list), optionally enriched
by minidump_stackwalk if installed. Adds ai_knowledge facts for exception
codes + faulting-module signatures, a MinidumpDialog, and CLI parity via
`rigdoctor ai dump <file>`.
