⚡ Bolt: [performance improvement] - #398
Conversation
💡 What: Changed `push_tab_to_leaf` to accept `&SurfaceId` instead of an owned `SurfaceId`. 🎯 Why: The previous implementation eagerly cloned `new_tab_id` inside `.any()` at each split node level during pane tree traversal, causing redundant heap allocations. 📊 Impact: Eliminates O(N) redundant `String` allocations (where N is the depth of the split tree) when pushing new tabs to a leaf pane. 🔬 Measurement: Profiling allocation calls during heavy pane splitting/tab creation will show reduced `String::clone` invocations.

| ## 2024-05-24 - [Avoid eager allocations in tree traversal callbacks] | ||
| **Learning:** In Rust, avoid calling `.clone()` on values like `String` inside iterator closures such as `.any()` during tree traversals. This causes eager, redundant allocations when deferring the `clone()` inside the callback match point saves unnecessary heap allocations. | ||
| **Action:** Pass references down the call stack for search predicates, and only invoke `.clone()` once the insertion or match point is definitively reached. |

This commit creates a new .jules/ root bucket solely for a generic automation-tool learning note; it is not used by ForkTTY's product, build, or contributor documentation. The repository requires new top-level directories to represent durable categories of repository content, so omit this artifact or move genuinely project-specific guidance into an existing documentation location.
