refactor(cmp): replace nvim-cmp with blink.cmp (#1568)

* refactor(cmp): replace nvim-cmp with blink.cmp

* refactor(cmp): use compatiable menu style

* fix: copilot comments

* refactor(lsp): centralize blink capabilities

* feat(completion): port blink cmp sources

* perf(completion): fix mason and other plugin loading order in `cmdline`

Signed-off-by: charliie-dev <mail@charliie.dev>

* perf(blink): limit `lazydev` source only on `ft=lua`

Signed-off-by: charliie-dev <mail@charliie.dev>

* chore(blink): enable type hint for `blink.cmp`

Signed-off-by: charliie-dev <mail@charliie.dev>

* chore(completion): remove luvit-meta dependency from lazydev

* fix(utils): guard nil colors_name and correct @PARAM typo

* fix(utils): surface require errors in extend_config

* feat(blink): show source-specific icon for ripgrep completions

Add icons.cmp[ctx.source_id] lookup before kind-based icon fallback
so the ripgrep icon (and other source icons) renders in the menu.
