feat(projman): add structured progress comments for real-time visibility (#232)

Add structured progress comment format for agents:
- Standard format with Status, Phase, Tool Calls budget
- Completed/In-Progress/Blockers/Next sections
- Clear examples for starting, blocked, and failed states
- Guidance on when to post (every 20-30 tool calls)

Update sprint-status.md:
- Document how to parse progress comments
- Show enhanced in-progress display with tool call tracking
- Add progress comment detection to blocker analysis

This enables users to see:
- Real-time agent progress
- Tool call budget consumption
- Current phase and step
- Blockers as they occur

Closes #232

+## Progress Comment Parsing
+
+Agents post structured progress comments in this format:
+
+```markdown
+## Progress Update
+**Status:** In Progress | Blocked | Failed
+**Phase:** [current phase name]
+**Tool Calls:** X (budget: Y)
+
+### Completed
+- [x] Step 1
+
+### In Progress
+- [ ] Current step
+
+### Blockers
+- None | [blocker description]
+```
+
+**To extract real-time progress:**
+1. Fetch issue comments: `get_issue(number)` includes recent comments
+2. Look for comments containing `## Progress Update`
+3. Parse the **Status:** line for current state
+4. Parse **Tool Calls:** for budget consumption
+5. Extract blockers from `### Blockers` section
+
+**Progress Summary Display:**

+       Status: In Progress | Phase: Testing | Tool Calls: 67/100

 ## Blocker Detection
 
 The command identifies blocked issues by:
-1. **Dependency Analysis** - Uses `list_issue_dependencies` to find unmet dependencies
-2. **Comment Keywords** - Checks for "blocked", "blocker", "waiting for"
-3. **Stale Issues** - Issues with no recent activity (>7 days)
+1. **Progress Comments** - Parse `### Blockers` section from structured comments
+2. **Status Labels** - Check for `Status/Blocked` label on issue
+3. **Dependency Analysis** - Uses `list_issue_dependencies` to find unmet dependencies
+4. **Comment Keywords** - Checks for "blocked", "blocker", "waiting for"
+5. **Stale Issues** - Issues with no recent activity (>7 days)
