Changes show as "Untitled Change" when following official proposal template

[virakngauv]

TL;DR when running openspec show [change-id] --json --deltas-only, I get title as "Untitled Change" because the change template doesn't include a title by default.

$ openspec show update-game-rules-codenames-compliance --json --deltas-only
Warning: Ignoring flags not applicable to change: scenarios
{
  "id": "update-game-rules-codenames-compliance",
  "title": "Untitled Change",
  "deltaCount": 0,
  "deltas": []
}

Description

When users create change proposals following the official AGENTS.md template, the
openspec show command displays "Untitled Change" instead of the actual change title.

Reproduction Steps

1. Initialize OpenSpec: openspec init
2. Create a proposal following the template in AGENTS.md (without title header)
3. Run: openspec show --json --deltas-only
4. Observe: "title": "Untitled Change"

Root Cause

The issue is a mismatch between the proposal template and the title extraction logic:

Template location: src/core/templates/agents-template.ts (lines ~159-177) The template
shows this proposal structure:

## Why
[1-2 sentences on problem/opportunity]

## What Changes
- [Bullet list of changes]
- [Mark breaking changes with **BREAKING**]

## Impact
- Affected specs: [list capabilities]
- Affected code: [key files/systems]

Code location: src/commands/change.ts (line ~122) The extractTitle function expects:

private extractTitle(content: string): string {
  const match = content.match(/^#\s+(?:Change:\s+)?(.+)$/m);
  return match ? match[1].trim() : 'Untitled Change';
}

Expected Behavior

Changes should display their actual title instead of "Untitled Change" when users follow
the official template.

Proposed Fix

Update the proposal template in agents-template.ts to include the required title header:

# Change: [Name of change]

## Why
[1-2 sentences on problem/opportunity]

## What Changes
- [Bullet list of changes]
- [Mark breaking changes with **BREAKING**]

## Impact
- Affected specs: [list capabilities]
- Affected code: [key files/systems]

Alternative Solutions

1. Update extractTitle to generate a title from the change ID if no header is found
2. Make the title header optional and display the change directory name as fallback

Impact

• Severity: Medium (UX issue, doesn't break functionality)
• Scope: Template update only, no breaking changes
• Users affected: All new OpenSpec users following the official template

Additional Context

The regex supports both # Title and # Change: Title formats, but the template doesn't
include either, causing the fallback to "Untitled Change".
