+- 266fa2b: Fix word-internal underscores being incorrectly treated as incomplete markdown
+
+  Previously, underscores used as word separators (e.g., `hello_world`, `snake_case`) were incorrectly identified as incomplete italic markdown, causing an extra underscore to be appended. This fix:
+
+  - Detects when underscores are between word characters and treats them as literals
+  - Preserves the streaming markdown completion for genuine incomplete italics (e.g., `_italic text`)
+  - Correctly handles trailing newlines when completing italic formatting
+
+  Fixes the issue where `hello_world` would become `hello_world_` when `parseIncompleteMarkdown` was enabled.
+
+- d583b1f: import `Lexer` only for possible tree-shaking
