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>`.

+### Added
+- **Import a crash dump (`.dmp`) and explain it with AI.** The **Games** page gains an
+  "Import crash dump…" button (shown once an AI provider is configured) that opens a Windows
+  minidump — the kind a Proton/Wine game writes when it hard-crashes — parses it, and hands the
+  result to the opt-in AI assistant (D24; cloud sends still ask first). A new stdlib
+  `core/minidump.py` reads the `MDMP` streams with `struct` (no new deps): the exception / crash
+  reason (e.g. access violation `0xC0000005`), the **faulting module** (which DLL the crash
+  address lands in — `nvwgf2umx.dll`, `d3d11.dll`, an anticheat, the game's own `.exe`…), OS/CPU,
+  and the loaded-module list. If `minidump_stackwalk` (Breakpad) or `minidump-stackwalk`
+  (rust-minidump) is on PATH, its fuller report is appended best-effort. The model is told the
+  dump came from a Windows process under Proton, so fixes stay Linux/Proton-side (Proton version,
+  DXVK/VKD3D, driver, launch options) — never Windows admin/registry steps. New `ai_knowledge`
+  facts cover the common exception codes and faulting-module signatures. CLI parity:
+  `rigdoctor ai dump <file>`.
