shellcheck findings in shell scripts

[ojongerius]

Hi!

While running shellcheck in my project it ran on node_modules and failed on bottleneck.

Minor shellcheck finding in scripts/test_all.sh:

Line 5 — source .env

• SC1091: Not following sourced file. ShellCheck can't follow non-constant or external sources.

Suggested fix — add a directive above the line:

# shellcheck source=/dev/null
source .env

Alternatively, running shellcheck with -x resolves this as well.

This is info-level only — just flagging it for completeness. Thanks for maintaining bottleneck!
