ce3204a350 docs(sync): record fast-seek root cause and splice bench trail
Splice bench (6.5 s, O(depth) shape confirmed), FatFS cluster-chain
root cause with elm-chan/ESP-IDF references, on-device fast-seek
verification, second localization round (strict-creation refuted,
read_header 470 ms), esp_map v2 design, and the two firmware plumbing
gaps (mwindow opts + 16-FD mount).

dade5e6bb3 docs(sync): record real-repo commit bench and TreeBuilder handoff
The real jcalixte/notes clone (570 MB pack, 1179 files) proved both index
strategies are O(N_tree) and unshippable: index.write re-hashes the tree
(611 s), and the index-free read_tree is 77 s cold and OOMs the mmap cache
(zlib crash). Record the run in the tradeoff curve, revise the verdict to an
O(depth) TreeBuilder walk, and add a handoff note with the design, firmware
call sites, and bench steps for the next session.
