[ENHANCEMENT] Indicate if execution was denied

[Shane32]

Problem (one or two sentences)

It's hard to tell when an execution is denied based on a rule. There's a green or red dot that appears next to the label "Running", which I believe is based on whether the command succeeded or failed.

But unless you're knowledgeable, the red dot doesn't mean it didn't run, but that it did run and execution failed (e.g. failed test run). This is confusing to me. Further, we don't get any dot when it did not run:

It even says "Running" which is false, as it was denied execution.

Context (who is affected and when)

Anytime automatic execution is enabled.

Desired behavior (conceptual, not technical)

I suggest, when execution is denied (automatically or manually), displaying a red X instead of a red/green dot, and changing the word "Running" to something else like "Running (denied)" or "Attempted run (denied)" or "Attempted execution (denied)" or something to indicate that the attempt was manually denied or automatically denied based on the configured rules.

I've analyzed this issue and here's my proposed implementation plan:

Problem Summary

When a command execution is denied (either automatically by rules or manually), the UI currently shows "Running" without any indicator dot, which is confusing since the command was never actually executed.

Proposed Changes

1. Add a new "denied" status to CommandExecutionStatus

File: packages/types/src/terminal.ts

• Add a new status variant "denied" to the commandExecutionStatusSchema discriminated union with an optional reason field (e.g., "auto_denied" or "user_denied")

2. Send "denied" status when command is rejected

File: src/core/task/Task.ts

• When a command is denied (either via auto-approval rules or manually), send a commandExecutionStatus message to the webview with status: "denied"

3. Update CommandExecution.tsx to show denied indicator

File: webview-ui/src/components/chat/CommandExecution.tsx

• Add handling for status?.status === "denied" to show a red X icon (using lucide-react's XCircle or Ban icon) instead of the green/red dot

4. Update ChatRow.tsx to show "Denied" label

File: webview-ui/src/components/chat/ChatRow.tsx

• Modify the icon/title logic for command type to check if the command was denied and show appropriate text like "Execution Denied" instead of "Running"

5. Add translation keys

File: webview-ui/src/i18n/locales/en/chat.json (and other locales)

• Add new keys under commandExecution:
  • denied: "Execution Denied"
  • autoDenied: "Auto-denied by rules"
  • userDenied: "Denied by user"

Visual Changes

• When denied: Show a red X icon with "Execution Denied" or "Denied" text
• Keep the existing green/red dot for commands that actually ran (success/failure)
• The command block will still be visible so users can see what was attempted

This approach maintains backward compatibility while providing clear visual feedback when execution is denied.

Please mention @roomote in a comment saying that you approve this plan, and I'll proceed with the implementation.
