fix: keyboard layout map, picker type tabs as filters, add unit tests
1. Fix RU_TO_EN keyboard map in keyboardLayout.ts: - ч was mapped to 'c' (wrong), now correctly 'x' - с was mapped to 'v' (wrong), now correctly 'c' - ю was mapped to '.' (wrong), now correctly ',' - Full rewrite with standard QWERTY/ЙЦУКЕН positional mapping - Examples: dthcnfr→верстак, руддщ→hello, цщкдв→world all correct now 2. Root cause of search breaking after 3-4 chars: Old map had ч:'c', с:'v' swapped. So dthcnfr → 'верчиак' (wrong). Each character was mapped to wrong Cyrillic equivalent. 3. Add unit tests: keyboardLayout.test.js (39 tests, node-runner): - EN→RU: dthcnfr, ghbdtn, ntcn - RU→EN: руддщ, цщкдв, ышеш - Unicode safety: Latin c (U+0063) ≠ Cyrillic с (U+0441) - expandKeyboardVariants for mixed inputs - Edge cases: empty, single char, mixed case, numbers 4. InternalLinkPicker type tabs → filters (not search modes): - Store rawResults (all) + filtered results by activeType - Switching type tab no longer clears query or triggers new search - Just filters existing rawResults by selected type - Shows 'Нет результатов для этого типа' when filtered empty 5. Both GlobalSearch and InternalLinkPicker use same expandKeyboardVariants() All tests PASS, full build OK.
