fix(blink): use plain insertion instead of snippet.

Replace snippet-based insertion with plain text insertion for completion
items generated by LLMs. Since LLM responses already contain appropriate
indentation, using VSCode's snippet-style insertion mechanism would
cause unwanted double-indentation, as the editor attempts to apply
indentation rules on top of the pre-formatted text.

Note: Currently, plain text insertion has a known upstream issue where
the cursor position is incorrectly set to the end of the first suggested
line instead of the last line.

See Saghen/blink.cmp#1123 for progress.
