v0.3.0

Added

• Optional skills.private_source host setting (a local directory or a git URL, with an optional skills.private_ref) that fills skills/private/ before the skills install; git uses the account's own sign-in, without the setting nothing is fetched, and removing it removes the skills an earlier fill added (#57).
• README: a Built with section that lists each third-party project Crewship installs or builds on, with a link and its license (#73).
• Eleven public skills in skills/public/ with general working rules: code navigation, engineering standards, git and PR habits, IEEE documentation, operating rules, Opus speed, process safety, progress bars, quality gates, talk style, and tooling conventions; a test fails when a public skill holds a private detail such as a home path, an email or a host address (#85).
• Generic global instructions in config/AGENTS.md, installed by the agents profile as ~/.claude/CLAUDE.md, ~/.omp/agent/AGENTS.md and ~/.codex/AGENTS.md; a file changed on the host is moved to a timestamped backup first, and an unchanged apply changes nothing (#86).
• Optional crew board (factory.board, ./ship.sh dock --board, or a new-host question): apply builds crewboard/ with cargo and runs it as the user service crewboard.service with a memory limit; without the key, apply stops and removes the service and the binary (#95).

Changed

• Each pull request adds its changelog entry as its own file, changelog.d/<issue>.<type>.md, and no longer edits CHANGELOG.md, so pull requests that run at the same time do not conflict; the release step assembles the files into CHANGELOG.md with towncrier build, and CI fails a pull request without a fragment unless it has the no changelog label (#90).
• README: the install part is labeled command blocks, and host sizing is one sentence (#91).
• Deployments link each GHCR image push to the package page and each landing page deploy to https://crewship.si instead of its workers.dev address (#102).
• The README tagline, the landing page description, and the npm package description are now "Orchestrate hundreds of agents effortlessly - hardware is the limit." (#105).
• The README now links to CREDITS.md for the full third-party list (#115).

Fixed

• npx crewship --help and install.sh --help print the usage and change nothing; a bad option prints the usage and exits with an error (#94).
