v0.5.0

Added

• --bridge-port CLI argument to override the bridge connection port —
  shorthand for --bridge-url ws://localhost:PORT. When a full
  --bridge-url / PFC_MCP_BRIDGE_URL is also supplied, only its port is
  overridden.

Changed

• pfc_execute_task now submits over the bridge's execute_task message
  (renamed from pfc_task so the shared bridge protocol is product-neutral;
  the bridge keeps pfc_task as a deprecated alias). Requires
  itasca-mcp-bridge >= 0.1.5 — older bridges silently ignore the message
  and submission times out. If that happens, confirm the bridge version with
  pfc_execute_code (import itasca_mcp_bridge; print(itasca_mcp_bridge.__version__)) and upgrade by re-running addon.py.
• Slimmed pfc_check_task_status pagination to total_lines + line_range,
  replacing the heavier pagination object. Output windows are still selected
  with skip_newest / limit / filter_text.
• Bumped itasca-mcp-bridge to 0.1.5 (submodule pin). Picks up the PySide6
  Qt task-pump fix so the bridge starts on PFC 9.7+ (Python 3.10 / Qt6),
  where a hard PySide2 import previously froze the GUI on startup, and the
  execute_task protocol rename.
