akm 0.5.0 Unifies Developer Workflows with Multi-Wiki, Vault, and Stash Sync Support

akm 0.5.0 transforms the stash from a simple asset storage into a comprehensive knowledge and workflow management platform. The release introduces wikis, workflows, and vaults as first-class citizens, plus writable stash support for syncing changes back to git—enabling AI agents to manage complex multi-step procedures with persistent, structured state. By removing LLM dependency from wiki operations, akm maintains predictable performance while giving developers and agents better control over knowledge bases, workflows, and secret management.
