v3.0.2

Added

• Reasoning effort now works in panel configs for codex, claude_code, and kiro, and can be pinned per
  seat. A panel seat (and a Target) takes an effort tier, so one voice can run at xhigh while another
  runs at high; a per-seat tier overrides the call-level effort, which overrides the per-agent / global
  config default. A new max tier joins the scale (claude_code and kiro reach it; codex and cursor
  clamp it to xhigh).
• Effort is delivered over ACP through each agent's real, self-described knob. codex and claude_code
  expose effort as an ACP config option (reasoning_effort / effort), so Rutherford reads the agent's
  advertised option at session open, clamps the requested tier to the values it actually offers, and sets it
  via session/set_config_option -- covering claude_code (previously a silent no-op) and a codex seat
  with no pinned model. kiro takes the --effort launch flag; codex with a pinned model keeps encoding
  the tier in the model id (model[effort]). An agent that advertises no effort knob is an honest no-op
  (effort_applied stays null), never a false claim.

Fixed

• Windows: an agent whose npm launcher resolved to its extensionless bin failed to start (WinError 193
  -- e.g. codex-acp / claude-agent-acp when shutil.which returned the Unix shell-script bin that shadows
  the .cmd / .ps1 siblings on PATHEXT resolution). prepare_argv now resolves the sibling shim, so the
  agent launches with clean JSON-RPC stdio instead of reporting not_installed.
