Subject: Chore: Move build scripts to repo root scripts/

The dylib build scripts are development tools, not extension bundle
assets. Moves them from Zig.novaextension/Scripts/ to scripts/ and
updates paths so the dylib lands in Zig.novaextension/Syntaxes/.

+# build-parser.sh — Compile the Nova-compatible tree-sitter-zig parser.
+#
+# Purpose:
+#   Build vendor/tree-sitter-zig/src/parser.c into a universal macOS dylib
+#   that Nova loads via its private SyntaxKit framework.
+#
+# What it does:
+#   - clang -dynamiclib for arm64 + x86_64
+#   - links against Nova’s SyntaxKit framework (from /Applications/Nova.app)
+#   - sets rpath @loader_path/../Frameworks so the dylib finds SyntaxKit
+#     when Nova loads it from the bundled extension
+#   - ad-hoc codesigns the dylib (Gatekeeper requirement)
+#   - writes the result to Zig.novaextension/Syntaxes/libtree-sitter-zig.dylib
+#
+# Usage:
+#   ./scripts/build-parser.sh
+#
+# Environment overrides:
+#   NOVA_APP   Path to Nova.app (default: /Applications/Nova.app)
+#   SDKROOT    macOS SDK path   (default: `xcrun --show-sdk-path`)
+#
+# Requirements:
+#   macOS, Xcode Command Line Tools (clang + xcrun), Nova installed.

+#
+# update-parser.sh — Bump vendored tree-sitter-zig and rebuild the dylib.
+#
+# Purpose:
+#   Refresh the vendored snapshot under vendor/tree-sitter-zig/ to a newer
+#   upstream commit, update VENDORING.md, and rebuild the parser dylib.
+#
+# What it does:
+#   - clones tree-sitter-grammars/tree-sitter-zig into a temp dir
+#   - checks out the requested ref (default: HEAD of the default branch)
+#   - exits early if the upstream SHA matches the pinned SHA
+#   - replaces src/, queries/, grammar.js, tree-sitter.json, LICENSE
+#     with the upstream copies; leaves VENDORING.md and README.upstream.md
+#     untouched
+#   - rewrites the "Pinned commit:" line in VENDORING.md
+#   - invokes build-parser.sh to rebuild Syntaxes/libtree-sitter-zig.dylib
+#   - prints a GitHub compare link for the diff
+#
+# Usage:
+#   ./scripts/update-parser.sh           # bump to upstream HEAD
+#   ./scripts/update-parser.sh <ref>     # bump to a tag, branch, or SHA
+#
+# Caveats:
+#   - any local edits inside the listed paths are overwritten — review
+#     `git diff vendor/` afterwards before committing
+#   - parses VENDORING.md by an exact "Pinned commit: <sha>" line prefix;
+#     keep that line format intact
+#
+# Requirements:
+#   git, plus everything build-parser.sh needs.
