feat: use interactive shell mode in JS isolation environments to source startup files#83

Adding CLAUDE.md with task information for AI processing. This file will be removed when the task is complete. Issue: #79
Add getShellInteractiveFlag() to js/src/lib/isolation.js that returns '-i' for bash and zsh, mirroring the existing Rust implementation. Apply the interactive flag in Docker and SSH isolation environments so that startup files (.bashrc, .zshrc) are sourced when running commands. This makes tools like nvm, rbenv, and pyenv available in isolated commands. Before this fix, even though bash was correctly detected over sh, running `nvm --version` in a Docker container failed because bash was started in non-interactive mode and did not source .bashrc. With this fix: - Docker: `docker run <image> bash -i -c "nvm --version"` sources .bashrc - SSH: `ssh <host> bash -i -c "nvm --version"` sources .bashrc on remote - SSH attached mode now always uses the detected shell (was only used when --shell was explicitly specified), matching the Rust behaviour Also bump JS version to 0.24.0.

… refactor file size - Add changeset file (issue-79-interactive-shell-mode.md) describing the interactive shell mode feature for proper version management via CI pipeline - Revert manual version bump in package.json from 0.24.0 to 0.23.0 (versions are managed automatically by the CI/CD changeset workflow) - Remove manually added CHANGELOG.md section (changeset workflow handles this) - Refactor isolation.js to stay within 1000-line limit (was 1037 lines): - Condense shellInteractiveFlag if/else blocks using spread operator - Simplify getShellInteractiveFlag function and JSDoc comment - Remove redundant inline comments Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
In auto mode (no explicit shell specified), SSH login shells already source startup files like .bashrc through the login process. Wrapping commands with bash -i in this mode caused bash to suppress exit codes in non-TTY CI environments (bash -i -c "exit 42" returning 0 instead of 42). The fix restores the original auto-mode behavior of passing the command directly to SSH (ssh host command), while keeping the -i flag only when the user explicitly requests bash or zsh as the shell. This preserves both correct exit code propagation and the ability to source startup files when an explicit shell is requested. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…atting The JSDoc for getShellInteractiveFlag was expanded to 6 lines, causing the file to exceed the 1000-line limit after prettier formatted the ternary expressions in the SSH auto-mode fix. Compressed to a single-line JSDoc to stay within the limit. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
Fixes #79 — JavaScript implementation was missing the
-i(interactive) flag for bash/zsh in isolation environments.The Rust implementation (merged in #82) already had this fix, but the JavaScript version was still at 0.23.0 without the interactive flag.
Root cause
Even though bash was correctly auto-detected over sh (added in 0.22.0/0.23.0), running
nvm --versionstill failed because bash was started in non-interactive mode:nvmis only available after.bashrcis sourced, which only happens in interactive mode (bash -i).Changes
getShellInteractiveFlag()function injs/src/lib/isolation.jsthat returns'-i'for bash/zsh (mirrors Rust'sget_shell_interactive_flag())-iflag in Docker attached and detached modes-iflag in SSH attached and detached modes--shellwas explicitly set), aligning with the Rust behaviourResult
