feat: Integrate learning modules into task managermakima/add-learning

When tasks complete (success or failure), the task manager now:
- Creates a ProgressLogEntry with task status and timestamp
- Extracts learnings from Claude output using extract_learnings_from_output
- Gets list of changed files from git diff
- Appends the entry to progress.log in the task's worktree

This enables cross-task learning where future tasks can benefit from
patterns, gotchas, and tips discovered during previous task executions.
