# --- cs (code spelunker) builder ---
# Builds a patched, statically-linked `cs` binary for the search_code tool.
# Pinned to the v3.1.0 commit for reproducibility; the patch adds Luau
# declaration support and corrects fuzzy edit-distance matching (see
# docker/cs/luau-declarations.patch and docker/cs/fuzzy-distance.patch). cs vendors its
# dependencies, so the `go build` step is offline after the clone.

# ─── Roblox Luau tooling (luau-lsp + rojo) ──────────────────────
# The LSP test bed under references/stunt-olympics/ drives Dispatch's
# luau-lsp integration: diagnostics-on-write and the `lsp` tool. Both
# `luau-lsp` and `rojo` must be on PATH inside the container (luau-lsp's
# sourcemap.autogenerate shells out to `rojo sourcemap --watch`). The base
# oven/bun image ships neither curl nor unzip, so install those first.
#
# Versions are pinned for reproducible builds; bump via --build-arg.
