fix: avoid gum pager in tests

[satyaborg]

Summary

• Keep in-process helper tests from detecting host gum/fzf binaries.
• Run the view_file helper test while TUI mode is disabled so release runs cannot block on gum pager.

Test plan

• bash scripts/devloop_test.sh under a PTY
• bash scripts/devloop_test.sh
• ./scripts/release.sh patch --dry-run
• ./scripts/release.sh patch --publish --dry-run
