chore: Use shared volume for pre-commit cache#305
Closed
Conversation
Instead of mounting the user's local cache. For the first use this will be slower (if the user has previously used uv) but using a separate volume means links within the cache referring to devcontainer locations will not interfere with uv being run from outside the container. Using a named volume means devcontainers for multiple projects can share the same cache.
Once the uv cache has been set up, configuring the pre-commit hooks takes the most significant amount of time building the container. Using a shared volume for the pre-commit cache as well takes the devcontainer re-build time from ~1m10s to ~10s.

Supercedes #304 and #305 by adding a global volume that contains: - pre-commit cache - uv cache - uv managed python cache - the venvs for all the projects This allows us to use hardlink mode which makes it even faster, and avoid the issue of anonymous volumes in devcontainers being left dangling. Added docs to say that there is now a global venv for the container, which is different for how it would look without any environment variables set
