Bump Hayabusa 2.17.0→3.8.1, Takajo 2.6.0→2.15.1; fix takajo CWD

Upstream renamed release assets (linux-intel → lin-x64-gnu,
linux-arm → lin-aarch64-gnu); updated accordingly.

Takajo was silently failing because start.sh invoked it from
WORKDIR=/data — takajo checks for companion files in CWD and
exits with "The Takajo executable does not exist in the current
directory." Wrap the call in (cd /opt/hayabusa && ./takajo ...)
so automagic reports actually land in /output/takajo/.

Also add .dockerignore to keep test-data/ and .git/ out of the
build context.
