Syntax highlighting breaks for multi-line Python constructs in partial diffs

[Avein]

When a try/except spans a hunk boundary and the opening keyword isn't included in the diff context, Shiki loses context and highlighting breaks for the visible lines. Root cause: highlighting is applied to hunk text only, not the full file.

Fix suggestion: fetch the full file via git show <sha>:<path>, highlight it with Shiki, then extract only the relevant line ranges

Partially addressed in 83b1f02 — added delimiter balancing for Python triple-quoted strings (""" and ''').

When a diff hunk starts inside a docstring, tree-sitter sees an unmatched """ and misparses everything after it. The fix counts delimiter occurrences per hunk and prepends a balancing one if the count is odd. Same approach used for JS/TS template literals and Go raw strings.

What's fixed: hunks that start inside """...""" or '''...''' multi-line strings now highlight correctly.

What's not fixed: block structure context (try/except, if/else, def, class:) — these aren't paired delimiters so they can't be balanced with parity counting. Fixing those would require fetching full file context via git show, which is a bigger architectural change.

can you upload an example url with the issue?

this is mostly fixed for js comments in https://github.com/remorses/critique/releases/tag/critique%400.1.134
