v0.4.0

Added

• On-demand agent install: Gemini and OpenCode are lazily installed on first boss open instead of being baked into the image
• Agent instruction files: Global package-install guidance provisioned per agent (CLAUDE.md, AGENTS.md, GEMINI.md)
• Development guide: Documentation for source builds and dev image workflow

Changed

• boss stop grace period reduced from 30s to 10s (container exits immediately on SIGTERM; 10s is ample for agent flush)
• boss init reads image from config exclusively; removed legacy DEFAULT_IMAGE migration
• Reorganized repo: assets/ moved into docs/assets/, vitest configs moved into config/
• CI splits integration tests into self-contained and external jobs

Fixed

• boss start hangs when Podman machine is not running on macOS
• boss init always pulls mutable image tags; falls back to cached image when pull fails
• SELinux EPERM on volume files across container restarts on macOS (gated label=disable to Podman-machine platforms only)
• Integration tests now locally runnable on macOS (isolated volumes, staleness detection, raised timeouts)
• On-demand agent symlink activation replaces direct mise shim approach

Security

• Updated trivyignore for two new CVEs in container image
