Entity-level diff/blame as an alternative to line-level in Helix

[rs545837]

Helix already uses tree-sitter for syntax highlighting, textobjects, and indentation. What if it could also use tree-sitter to show diffs and blame at the entity level (functions, structs, classes) instead of lines?

I've been building sem, an open source CLI that does exactly this. It parses code with tree-sitter, extracts semantically meaningful chunks, and gives you structural diffs, blame, and impact analysis. Supports 20+ languages.

Since Helix already has the tree-sitter infrastructure, curious if there's interest in this kind of integration. Could imagine sem diff output in a picker, or entity-level blame in the gutter instead of line-level.

Would love to hear thoughts from the community.
