kistaro 3f209efa89 Add v0.1 scaffold: tree-sitter-p8-cart grammar and Zed extension
The grammar parses the .p8 cartridge container ( header, version, and
the named __lua__/__gfx__/__gff__/__label__/__map__/__sfx__/__music__
sections, plus a fallback unknown_section ). The Zed language definition
hands the __lua__ body to Zed's built-in Lua via injections.scm, so
non-dialect Lua code highlights correctly today; PICO-8-specific syntax
(?, +=, !=, single-line if, etc.) will fall back to error highlighting
in those regions only — see README roadmap for the dialect grammar fork.

; Inject Lua syntax highlighting into the __lua__ section.
;
; NOTE: This injects Zed's built-in Lua grammar, which does not
; understand Pico-8 dialect extensions ( ?, +=, !=, single-line
; `if (cond) stmt`, binary literals, memory peek prefix operators,
; etc. ). Code that uses those forms will produce parse errors
; locally, with degraded highlighting in those regions only — the
; rest of the file will still render correctly. A future Pico-8
; Lua grammar fork will replace this; see README for status.
