Gregorio GABC — Zed Extension

Adds support for GABC/NABC (Gregorian chant notation) files to Zed.

Features

• Syntax Highlighting — Full highlighting for GABC headers, pitches, clefs, neumes, bars, alterations, style tags, NABC notation, and comments.
• LaTeX Injection — TeX code inside <v>…</v> tags and verbatim attributes ([nv:…], [gv:…], [ev:…]) gets LaTeX highlighting.
• Bracket Matching — Auto-matching for (), [], {}, and <>.
• Code Outline — Headers appear in the document outline/symbols panel.
• Language Server — Diagnostics, hover, completion, and document symbols via gregorio-lsp.
