📝 Walkthrough

Walkthrough

Release tooling now uses .bash script names, preserves errexit in command substitutions, and checks all release-tool Bash scripts with ShellCheck.

Changes

Release tool Bash migration

Layer / File(s)	Summary
Bash error handling release-tools/*.bash	Release scripts and fake test executables enable Bash inherit_errexit.
Release tool checks and wiring flake.nix	Release commands reference .bash scripts. The release-tools check runs test.bash and adds ShellCheck coverage for all .bash files.
