Lataa arf console 0.2.6

Release Notes
Added
- Experimental: Headless mode (arf headless) for running R without the interactive REPL, controlled entirely via JSON-RPC IPC. Designed for AI agents and CI environments where a terminal is not available (#119, #122, #123, #124, #125, #126)
- --bind, --pid-file, --quiet, --log-file options and graceful shutdown on SIGTERM/SIGHUP
- --json flag to output session info as JSON on startup, enabling programmatic discovery of socket path and session details (#130)
- Persists evaluated commands to history database with session-scoped isolation via unique session IDs (#133, #134)
- Experimental: IPC history method and arf ipc history CLI subcommand for querying R command history from external tools (#136)
- Experimental: IPC session info (arf ipc session, arf ipc list) and session file now include log_file field, exposing the headless mode log file path for debugging and monitoring
Changed
- Experimental/Breaking: All arf ipc subcommands now output JSON to stdout (pretty-printed on terminal, compact when piped) (#137)
- Commands that previously used plain text (list, eval, send, shutdown) now return structured JSON
- Errors are written to stderr as JSON objects of the form {"error": {"code": "...", "message": "...", "hint": ..., "data": ...}} with all fields always present (null when not applicable) for a fixed schema
- Exit codes now indicate error category: 2 (transport), 3 (session), 4 (protocol)
- Experimental/Breaking: arf ipc eval no longer exits with code 1 for R evaluation errors. R errors are returned as part of the JSON response (exit 0) to distinguish from IPC failures. The value and error fields are always present (null when not applicable)
Removed
- Experimental/Breaking: Remove the arf ipc status subcommand, which is superseded by arf ipc session (returns a superset of the same information via IPC)
- Experimental: Remove send as a JSON-RPC method alias for user_input. The CLI subcommand arf ipc send is unchanged
