Subject: [PATCH] Minor cleanups: default TZ to UTC, shellcheck directive,
 comment clarity (#21)

- Default timezone to UTC instead of America/New_York
- Add shellcheck shell=bash directive to .zshrc
- Extract docker filter label into local variable in cmd_down
- Clarify mount filter comment (target paths immune to project name changes)
