Pull request overview

Adds provider/model tagging to the TUI’s HTTP request/response events so the selected model is visible directly in the event list.

Changes:

• Extend displayRecord to carry Provider and Model metadata and render it as a tag beside the endpoint label.
• Parse provider from the HTTP URL and model from the decoded JSON body (with a Gemini URL fallback).
• Add unit tests covering OpenAI model extraction, Gemini URL model extraction, and localhost-as-local provider detection.

Pull request overview

This PR adds provider/model “model tags” to the TUI for HTTP request/response events by extracting model metadata from the HTTP payload/URL and rendering it inline in the event list.

Changes:

• Extend displayRecord with Provider/Model fields and render a colored model tag next to the endpoint label in the list view.
• Parse HTTP events to infer provider from request URL and model from the request body (with a Gemini URL fallback).
• Add unit tests to validate provider/model extraction for several providers and an unknown provider case.

• renderRecordLine only truncates record.Summary; with the new model tag, label/prefix can easily exceed contentWidth (e.g., narrow terminal or long model name), causing lines to wrap or overflow the viewport. Consider truncating the model tag (or the full label) based on remaining width before building prefix, so lipgloss.Width(prefix) never exceeds contentWidth.

	labelParts := []string{style.Render(record.Endpoint)}
	if record.Model != "" {
		labelParts = append(labelParts, modelTagStyle(record.Provider).Render(record.Model))
	}
	label := lipgloss.JoinHorizontal(lipgloss.Left, labelParts...)
	cursor := "  "
	if selected {
		cursor = cursorStyle.Render("> ")
	}
	link := renderPairLink(annotation)
	prefix := lipgloss.JoinHorizontal(lipgloss.Left, cursor, ts+" ", link, label, " ")
	summaryWidth := max(0, contentWidth-lipgloss.Width(prefix))
	return lipgloss.JoinHorizontal(lipgloss.Left, prefix, truncateText(record.Summary, summaryWidth))
