Rename timeline lanes: double-click a lane's label in the gutter to give it a name ("Music", "Voice-over"...).

• ProjectConfiguration::track_names, keyed "<track>:<lane>" (for example audio:1), #[serde(default)].
• A small rename dialog. Enter confirms, Escape cancels, and an empty name restores the track's own label. One undo step.
• track_chip shows the name, and TimelineModel carries the names so drawing doesn't touch the project.

Testing: cargo test --bin cap-gpui (new lane_names_come_from_the_project_by_track_and_lane).

Thanks @YoavLevavi, lane names are handy, and the dialog follows the preset dialog's patterns nicely (Enter/Escape, one undo step, an empty name restores the default). One functional issue: names are keyed "<track>:<lane>", but lanes can be reordered by dragging the gutter, and finish_lane_reorder (apps/desktop-gpui/src/editor_window.rs:4555) rewrites every segment's track through edits::reorder_track_lane / edits::reorder_overlay_track without touching track_names. If you name lane 1 "Music" and drag it above lane 0, the music now sits on lane 0 while lane 1, holding the other audio, is still called "Music". Could you remap project.track_names with the same from/to shift in those reorder paths (in the same edit, so it stays one undo step) and add a test for it? Two smaller things: track_name_key was inserted between track_chip and its doc comment (apps/desktop-gpui/src/editor_timeline.rs:1791-1798), so please move it above that comment. And please add skip_serializing_if = "std::collections::BTreeMap::is_empty" to track_names (crates/project/src/configuration.rs:2686), so projects without names save unchanged, the way #2781 does for locked_tracks.
