fix: resolve CI failures with Bazel-native Go toolchain integration

avrabe · avrabe · commit 204e59cbc5e4 · 2025-07-29T15:32:36.000+02:00
Fix Production Readiness CI failures by modernizing Go toolchain usage
and removing security-risk placeholder checksums.

Fixes applied:
- Replace system Go dependency with Bazel's native Go toolchain in tinygo_toolchain.bzl
- Add explicit Go SDK configuration in MODULE.bazel (Go 1.24.4)
- Remove all placeholder checksums from tool_versions.bzl (security risk)
- Clean up obsolete tool version entries that aren't used by default

Technical improvements:
- TinyGo toolchain no longer requires system Go installation
- Eliminates "No Go installation found" CI failures
- Uses rules_go Go toolchain integration for consistency
- Maintains wit-bindgen-go integration through build-time Go binary rules

Security improvements:
- Removes all "NEED_REAL_CHECKSUM" placeholders that triggered CI security validation
- Consolidates tool versions to only supported, checksummed releases
- Ensures all remaining checksums are valid SHA256 values

This resolves both the macOS CI Go installation failures and the security
validation failures while maintaining full toolchain functionality.
