fix: suppress flow console panels in TUI mode; clear header agent on method change

Two review follow-ups:

1) Method panels break Textual TUI (Cursor): forcing suppress_flow_events off
   so the STEPS panel receives events also un-gated the EventListener's Rich
   flow/method panels (ConsoleFormatter.print_panel prints is_flow=True panels
   regardless of verbose), which interleave with Textual and corrupt the TUI.
   print_panel now skips is_flow panels when is_tui_mode() is set (the same
   context the TUI worker already establishes and the tracing listeners already
   honor). Non-TUI/headless flow runs are unaffected. Test:
   test_console_formatter_tui_mode.

2) Flow header showed a stale agent (CodeRabbit): _current_agent persisted
   across methods. It's now cleared when a method starts and when the active
   method changes, so the header never shows the previous method's agent until
   a new agent event arrives. Test: test_flow_method_transitions_clear_current_agent.
