The kilo-cli artifact ballooned from ~1 GB to 1.83 GB after the codebase
indexing PR started emitting external sourcemaps and copying tree-sitter
wasms per target. The resulting 1.83 GB artifact triggered a silent
partial-extract in actions/download-artifact@v4 during build-vscode,
causing the 2026-04-29 publish run to fail with 'CLI binary not found'.
- Skip external sourcemaps in release builds (~620 MB saved across
12 targets); dev builds still emit maps for local debugging.
- Exclude any stray .map files from the CI artifact and skip zstd
compression on binaries (saves ~60 s on upload and reduces the
chance of partial-extract bugs on the download side).
