Add action to report GitHub Copilot Chat issues with output channel contents

[Copilot]

Adds workbench.action.chat.reportIssueWithOutput command to capture output channel contents and pre-populate the issue reporter.

Implementation

• New ReportChatIssueWithOutputAction in chatSetupContributions.ts
• Uses ITextModelService.createModelReference(channel.uri) to safely read output channel content via public API
• Attempts to retrieve GitHub Copilot Chat output channel, falls back to Window output channel (rendererLog) if unavailable
• Accepts optional issueTitle and issueBody parameters that are passed through to the issue reporter
• Pre-fills issue reporter data field with output channel contents or inlined localized fallback message
• Gated on ChatContextKeys.enabled and ChatContextKeys.Setup.installed
• Output channel ID extracted to defaultChat constant

Usage

// Basic usage via F1 command palette
F1 > "Report GitHub Copilot Chat Issue"

// Programmatic usage with optional parameters
await commandService.executeCommand('workbench.action.chat.reportIssueWithOutput');

// With custom title and body
await commandService.executeCommand('workbench.action.chat.reportIssueWithOutput', {
  issueTitle: 'Custom Issue Title',
  issueBody: 'Custom issue description'
});

Opens issue reporter with:

• GitHub Copilot Chat extension pre-selected
• Output channel contents (GitHub Copilot Chat or Window) in additional data field
• Optional pre-populated issue title and body
• Diagnostic logging for troubleshooting

Original prompt

Register another action around the chatSetup code that will grab the contents of GitHub Copilot Chat Output Channel and open the issue reporter with the contents as additional information

@copilot if the GitHub Copilot Chat output channel is not available, can you attach the Window output channel?

Also, can you allow the issue title and body (not data) to be passed in and plumbed through?

Done in commit 9b51a84:

• Falls back to Window output channel (rendererLog) when GitHub Copilot Chat output channel is not available
• Added optional options parameter with issueTitle and issueBody fields that are passed through to the issue reporter

Usage example:

// With default behavior
await commandService.executeCommand('workbench.action.chat.reportIssueWithOutput');

// With custom title and body
await commandService.executeCommand('workbench.action.chat.reportIssueWithOutput', {
  issueTitle: 'Custom Issue Title',
  issueBody: 'Custom issue description'
});

@copilot This can be inlined in the Action.

Done in commit fafa670 - moved the localize call inline in the Action.
