fix: disable blink.cmp remaps when telescope prompt is open (#104)

resolves #102

* disable blink.cmp remaps when telescope prompt is open

* make it a bit cleaner

* implemented iteration over exclude_filetypes table

* add `exclude_filetypes` config option to disable keymaps for specific filetypes

- Implemented `exclude_filetypes` as a config option with default values
(`TelescopePrompt`
- Improved performance by using a map for filetype lookups instead of
iterating over a list
- Keymaps are now disabled for buffers matching the excluded filetypes)

* add dynamic plugin disabling based on file type

- Implemented autocommand for BufEnter and InsertEnter events to disable
the plugin dynamically for specific file types.
- Added a global variable `vim.g.blinkcmp_enabled` to track whether the
plugin is enabled.
- Updated relevant parts of the plugin to return early if the plugin is
disabled for a file type.

* remove old unused code

* refactor: remove blinkcmp_enabled flag and directly utilize utils.is_special_buffer() for buffer handling

* refactor: remove extra calls to is_special_buffer where logic already exists
