Add remove view cone action

[SunkenInTime]

Summary

• add a Remove View Cone action to attached-agent context menus
• preserve agent identity, position, team, and state during conversion
• support undo/redo with exact view-cone geometry restoration
• retain page-transition mapping through the existing stable agent ID

This promotes the already-reviewed #127 change onto main; #127 was merged into #125 after #125 had already merged.

Validation

• fvm flutter test test/remove_view_cone_test.dart test/view_cone_agent_drag_feedback_test.dart
• fvm flutter analyze --no-fatal-infos (passes with one pre-existing deprecation info in pages_bar.dart)

Greptile reviewed the exact source commit in #127 at 5/5 with no findings.

📝 Walkthrough

Walkthrough

Adds view-cone removal through AgentProvider and the agent context menu. The conversion preserves agent properties and deletion state, records an action, updates provider state, and supports undo/redo.

Changes

View-cone removal

Layer / File(s)	Summary
Agent conversion contract lib/providers/agent_provider.dart	Adds convertViewConeAgentToPlain, which validates the target, preserves its properties and deletion state, records the edit, updates provider state, and returns success or failure.
Context-menu action and validation lib/widgets/draggable_widgets/agents/agent_widget.dart, test/remove_view_cone_test.dart, test/view_cone_agent_drag_feedback_test.dart	Adds the Remove View Cone action through ActionGroup.agent. Tests cover menu layout, conversion, no-op behavior, transition moves, undo, and redo.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 307b8

The change is merge-ready after normal checks. A minor follow-up could strengthen undo-test coverage for elevation restoration, but no actionable merge-blocking risk remains.

Cover visionElevation in the undo regression test.

The fixture leaves visionElevation null. The undo assertion cannot detect loss of a non-null elevation. Set a non-null elevation and assert that undo restores it.

Proposed test update

     final agent = PlacedViewConeAgent(
       id: 'view-cone-agent',
       type: AgentType.sova,
       presetType: UtilityType.viewCone90,
       position: const Offset(200, 300),
       rotation: 0.5,
       length: 75,
+      visionElevation: 2,
     );

Greptile Summary

This change adds a “Remove View Cone” action for attached view-cone agents. It converts the selected agent into a plain agent while preserving its identity and shared state, and records the change so it can be undone and redone.

The attached-agent context-menu flow and transaction behavior were exercised successfully. The targeted failure hypothesis was disproved: only the selected attached agent was converted, its ID and core state were retained, undo restored the complete view-cone geometry, and redo removed the cone again. No defects were found.

Confidence Score: 5/5

Safe to merge based on the exercised context-menu conversion and undo/redo flows.

The focused Flutter checks passed for both the shipped widget/provider coverage and a separate transaction scenario with multiple attached agents, confirming target-only conversion, state retention, geometry restoration on undo, and removal on redo.

Files Needing Attention: No files need follow-up attention.

T-Rex Logs

What T-Rex did

• Ran the Flutter test suites for remove_view_cone and view_cone_agent_drag_feedback, which exited successfully with 6 passing tests including the attached-agent context-menu removal and undo/redo flow.
• Executed the focused trex_remove_view_cone_transaction_test.dart and observed a successful run after exercising target-only conversion with a second attached cone, retained agent state, full geometry restoration on undo, and cone removal on redo.
