Fix Shift+A autocomplete interference with refined approach

- Replace single key sequence binding with multiple potential Shift+A sequences
- Add explicit self-insert bindings for 'A', '^[[1;2A', and '^[[65;2u' to cover different terminals
- Configure ZSH_AUTOSUGGEST_CLEAR_WIDGETS to prevent autosuggestion interference with vim modes
- Add vi-add-eol and vi-add-next to clear widgets to ensure proper vim behavior
- Set ZSH_AUTOSUGGEST_ACCEPT_WIDGETS to handle vim end-of-line operations correctly

This should prevent Shift+A from triggering autocomplete while preserving vim functionality.
