+# 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.
