Add RTK integration for token-optimized command output

When enableRtk is set in adapter config, the adapter:
- Adds an init container (curlimages/curl) to download the RTK binary
- Mounts RTK binary in the main container via shared emptyDir volume
- Runs `rtk install claude-code` before invoking Claude to set up hooks
- Disables RTK telemetry (RTK_NO_TELEMETRY=1) for automated environments
- Supports optional rtkVersion config for pinning specific versions

RTK filters CLI command output before it reaches the LLM context,
reducing token consumption by ~80%.
