Feature: Scope creep detection and alerts

[gloomcheng]

Problem

As a developer, I often realize too late that a task has expanded beyond the original estimate. By the time I notice, I've already spent 3x the planned hours.

Current State

Toki tracks time per issue automatically, but doesn't proactively warn when time exceeds estimates.

Proposed Solution

1. Track estimated vs actual - Allow setting time estimates per issue (from PM system or manual)
2. Threshold alerts - Notify when reaching 80%, 100%, 150% of estimate
3. Scope creep report - Weekly summary of tasks that exceeded estimates with patterns

Example

```
⚠️ Issue PROJ-123 has exceeded estimate
Estimated: 4h
Actual: 6h 23m (+60%)

Consider: Breaking into subtasks? Scope changed?
```
