v1.0.4

Improvement

Show error details for failed operations in sync command.

Previously, git-fleet sync only displayed summary counts like Pulled 0/1 repositories when operations failed, with no indication of why they failed. Now, failed repositories and their error messages are printed inline:

Step 2/4: Pulling repositories (smart)...
  Pulled 0/1 repositories
    ✗ matsuya-pwa: error: fetching ref refs/remotes/origin/... failed: incorrect old value provided

This applies to all three steps (fetch, pull, push) in both single-root and multi-root sync modes. Standalone pull/push commands already showed error details via their results table — this brings sync to parity.
