fix: extract human-readable title from spec.md when feature field is spec ID

When the implementation_plan.json feature field contains the spec directory
name (e.g., "054-version-2-5-5-displays-version-2-5-0-in-updater") instead
of a human-readable title, the task card and modal showed the ugly spec ID.

Now detects when the feature field looks like a spec ID (starts with 3 digits
and a dash) and extracts the actual title from spec.md's first heading,
handling prefixes like "Quick Spec:" and "Specification:".

Example: "054-version..." → "Fix Version 2.5.5 Display in Updater"
