v0.5.0

• Route every help request through the shared agent-first help renderer: the default is scoped structured JSON for one command level, --recursive returns a compact full-tree index, and --output plain restores conventional human help.
• Drop clap's help pseudo-subcommand and replace the eager help dump on a missing command with a compact structured error carrying a 'try: afslug --help' hint.
• Make --version always emit a structured AFDATA protocol result and remove the -V short alias so version discovery has exactly one machine-readable shape.
• Add a global --output-to flag (split, stdout, stderr) that defaults to split, sending result events to stdout and error events to stderr, with stdout selectable for a single ordered event stream.
• Upgrade the Agent-First Data dependency to 0.26.0 for the unified version/help pre-parser and output-routing emitter.
• Add a release workflow that builds macOS, Linux, and Windows binaries and publishes the checksums Homebrew and Scoop packaging consumes.
