Colby Mchenry c13bd0890f fix(wsl): keep WSL off Windows' index on /mnt drives, and explain the I/O error (#995) (#2061)
When Windows-native and WSL CodeGraph both open the same
.codegraph/codegraph.db under /mnt/<drive>/, SQLite's locking and -shm
shared memory don't hold across the 9p/DrvFs bridge and WSL fails with a
bare "disk I/O error".

- A SQLite I/O error on the default index of a WSL /mnt/<drive> project is
  rewritten (in the SQLite adapter, so every open and query is covered) into
  the CODEGRAPH_DIR=.codegraph-wsl instruction. MCP answers it success-shaped,
  and a failed default-project open is reported instead of "no project loaded".
- On WSL + /mnt/<drive> with CODEGRAPH_DIR unset, the data dir is resolved per
  root: an existing .codegraph-wsl/ wins, then an existing .codegraph/ index
  (kept, no silent re-index), else a fresh index goes in .codegraph-wsl/.
  `codegraph init` says where it went. Every other host is unchanged.
