P1 Badge Remove one-off .jules repo metadata

This adds a Jules task-learning note under a new top-level .jules/ directory. The root AGENTS.md repo-shape guidance says to keep root docs stable and to “Prefer adding a new top-level directory only for a durable category of repo content” (AGENTS.md:106-117); this file is task-specific agent metadata rather than a durable ForkTTY content category, so it violates that contract and leaves one-off automation artifacts in the repository. Please drop it or move any durable guidance into an existing scoped source-of-truth doc.

**Learning:** When searching recursively in a tree-like structure (e.g. `PaneTree` using `PaneNode`), passing string or collection ownership via `.clone()` to an iterator predicate like `.any()` leads to unnecessary allocations. The condition may fail in multiple children, resulting in an O(N) allocation overhead just to verify a negative match.
**Action:** When passing parameters that eventually need to be owned inside nested traversal functions, pass them as references through the call stack and invoke `.clone()` only at the exact point of true insertion/ownership.
