⚡ Bolt: [performance improvement]

[Lucenx9]

💡 What: Changed push_tab_to_leaf to return a Result<(), SurfaceId> instead of bool to thread the ownership of new_tab_id through the recursive search of PaneNode child nodes.
🎯 Why: The previous code cloned SurfaceId (a heap allocated String type) inside a .any() closure when searching the PaneNode::Split children array. This resulted in eager O(N) allocations for every single child node checked, even if the node was ultimately not a match.
📊 Impact: Reduces GC and memory allocation pressure by turning O(N) heap allocations into zero allocations during the search algorithm.
🔬 Measurement: The performance improvement can be measured via flamegraphs or memory profilers when extensively opening, closing, or rearranging tabs to observe reduced time spent in string clone operations.

📝 Walkthrough

Walkthrough

The recursive pane-tree tab insertion function now returns Result<(), SurfaceId>, threading ownership through failed searches instead of cloning. WorkspaceModel::add_tab handles the new result contract, and .jules/bolt.md documents the pattern.

Changes

Tab insertion refactor

Layer / File(s)	Summary
Result-based tab insertion crates/forktty-core/src/model/pane_tree.rs, crates/forktty-core/src/model.rs, .jules/bolt.md	push_tab_to_leaf propagates SurfaceId through Err on failed traversal, while add_tab checks .is_err() and the ownership pattern is documented.

Estimated code review effort: 2 (Simple) | ~10 minutes

Remove the bot-only root metadata directory

A repo-wide search finds no consumer of .jules/bolt.md, and this commit creates .jules/ solely for a generic bot learning note. This introduces an undocumented top-level content bucket despite the repository contract reserving new root directories for durable project-content categories; omit the note or place genuinely durable documentation under an existing owner.

646-675: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add regression coverage for the returned-ownership path.

The implementation looks correct, but the supplied crates/forktty-core/src/model/tests/pane_tabs.rs test covers only a single leaf. Add a case where the target is in a later split child to verify that Err(id) neither drops nor duplicates the tab ID.

As per coding guidelines, add behavior-boundary tests for model invariants during extraction or refactoring.
