Fix repl.sh and typecheck.sh to properly parse bild --plan JSON

The issue was that bild --plan outputs progress indicators before the
JSON, causing jq to fail parsing. Fixed by: - Using grep to extract
only lines starting with '{' (the JSON output) - This filters out
progress lines like '[…] target' - Restored typecheck.sh to use
repl.sh for proper environment setup

Now typecheck.sh correctly provisions the environment via repl.sh
instead of trying to use bild or raw python.
