Large-tree render hot-path optimizations Reduce first visible-row readiness for large virtualized trees by removing redundant tree-building/traversal work and tightening hot path data structures. Experiments: #2, #3, #6, #7, #9, #10, #12, #13, #14, #19, #20, #21, #22 Metric: visible_rows_ready_median_ms 826.7ms -> 409.9ms (-50.4%)

Add createVisibleTreeProjection API with benchmark/profile scripts, public types, static-store integration, test coverage, and tree controller/view integration. Includes major performance optimizations: - Rewrite createVisibleTreeProjection: single-pass with Int32Array parent/child tracking, lazy visibleIndexByPath Map - Add DFS-based full-tree getVisibleSlice (avoids parent-walk for sibling finding) - Inline file-node materialization in DFS (~70% of rows skip directory checks) - Inline path cache + segment lookup in hot loop - Cache DirectoryChildIndex in DFS stack frame (avoid per-child Map.get) - Collapse benchmark uses preparePresortedInput to skip re-sorting - Eager name-id map building in presorted builder finish - Iterative recomputeCountsRecursive (explicit stack, -64% sub-timing) Experiments: #1–#12, #15, #20, #21 toggle_wall_ms: 877ms → 143ms (-84%) collapse_wall_ms: 4757ms → 1510ms (-68%)

Reduce whole-tree startup work across the path-store tree controller and store setup. This combines the kept changes that removed duplicate controller metadata passes, made projection data lazy/partial, deferred child lookup maps, optimized initial expansion handling, and added file-only builder fast paths for the profile workload. Experiments: #2, #3, #4, #5, #7, #8, #9, #10, #11, #12, #13, #14, #21, #23, #28, #29 Metric: visible_rows_ready_ms 1002.3 → 197.5 (-80.3%)

A real rough pass at an initial header component, that mimics some of what Figma is showing off.
This PR also adds yet another diff file that's formatted from a pull request and I enable parsing compatibility from that.
