zeta: Scope edit prediction event history to current project (#37595 )
This change also causes Zeta to not do anything for editors that are not associated with a project. In practice, this shouldn't affect any behavior - those editors shouldn't have edit predictions anyway. Release Notes: - Edit Prediction: Requests no longer include recent edits from other projects (other Zed windows).

  - Example: avoid `let _ = client.request(...).await?;` - use `client.request(...).await?;` instead
 * When implementing async operations that may fail, ensure errors propagate to the UI layer so users get meaningful feedback.
 * Never create files with `mod.rs` paths - prefer `src/some_module.rs` instead of `src/some_module/mod.rs`.
+* When creating new crates, prefer specifying the library root path in `Cargo.toml` using `[lib] path = "...rs"` instead of the default `lib.rs`, to maintain consistent and descriptive naming (e.g., `gpui.rs` or `main.rs`).
+* Avoid creative additions unless explicitly requested
+* Use full words for variable names (no abbreviations like "q" for "queue")
+* Use variable shadowing to scope clones in async contexts for clarity, minimizing the lifetime of borrowed references.

+  ```rust
+  executor.spawn({

+      async move {

 We plan to set aside time each week to pair program with contributors on promising pull requests in Zed. This will be an experiment. We tend to prefer pairing over async code review on our team, and we'd like to see how well it works in an open source setting. If we're finding it difficult to get on the same page with async review, we may ask you to pair with us if you're open to it. The closer a contribution is to the goals outlined in our roadmap, the more likely we'll be to spend time pairing on it.
