tools/run.py --release still executes target/debug/goboscript

Repro

tmp=$(mktemp -d /tmp/goboscript-run-release-XXXXXX)
printf 'costumes "blank.svg";\n\n' > "$tmp/stage.gs"
printf '<svg xmlns="http://www.w3.org/2000/svg" width="1" height="1"></svg>\n' > "$tmp/blank.svg"

# simulate a clean tree with no debug binary
mv target/debug/goboscript target/debug/goboscript.bak
uv run tools/run.py --release "$tmp"
mv target/debug/goboscript.bak target/debug/goboscript

Observed:

Finished `release` profile [optimized] target(s) in ...
FileNotFoundError: [Errno 2] No such file or directory: 'target/debug/goboscript'

tools/run.py --release runs cargo build --release, but still invokes target/debug/goboscript for project builds. Parallel mode also hardcodes the same debug path.

Expected

--release should execute target/release/goboscript after building the release profile.
