Naming and leftover cleanup (accesibility.ts typo, stale .gitkeep) #200

Priority: P3

Context

packages/native/src/lib/helpers/accesibility.ts is misspelled while dom's file is accessibility.ts, so an agent searching for one misses the other. The .gitkeep files are leftovers in folders that now contain code.

Do

• Rename packages/native/src/lib/helpers/accesibility.ts to accessibility.ts and update the imports.
• Delete packages/dom/src/lib/.gitkeep and packages/native/src/lib/.gitkeep.

Done when

• git grep -i accesibility returns nothing.
• yarn check passes.
