v0.6.0

• Compile the CLI from a closed-world cli-spec-v1 registry — one source for argv parsing, typed values, legal combinations, output contracts, help, and docs/cli.md — and drop clap entirely
• Split skill status, install, and uninstall into two shapes each, so --skills-dir (which names a single directory) is rejected by the parser when the verb fans out across every agent, instead of by a runtime check documented only in prose
• Breaking: short flags no longer exist, so -V and -h are cli_unknown_argument rather than aliases; --recursive and --output markdown are replaced by --docs; and errors carry specific cli_* codes instead of a generic cli_error
• Upgrade the Agent-First Data dependency to 0.29.0
