Enhancement: Quick-pick common slice names from dropdown

[ecorkran]

Feature Request

Add a dropdown or autocomplete for common slice names to make slice creation faster and more consistent.

Current Behavior

Users must manually type slice names like:

• 900-slice.maintenance
• 100-slice.foundation
• 200-slice.feature-name

This leads to:

• Typos and inconsistent naming
• Need to remember common patterns
• Slower workflow for standard slices

Proposed Solution

Add a quick-pick dropdown or autocomplete to the "Current Slice" field with common slice names:

Common Slices (suggested defaults):

• 100-slice.foundation
• 200-slice.core-features
• 300-slice.ui-components
• 400-slice.integration
• 500-slice.testing
• 900-slice.maintenance
• 910-slice.bug-fixes
• 920-slice.refactoring
• 930-slice.documentation

Implementation Options:

Option 1: Combobox (Recommended)

• Searchable dropdown with autocomplete
• Can still type custom slice names
• Shows suggestions as you type
• We already have a Combobox component!

Option 2: Recent Slices

• Show recently used slice names
• Auto-populated from project history
• More dynamic than static list

Option 3: Hybrid

• Common slices + recent slices
• Best of both worlds

Benefits

• ✅ Faster slice creation workflow
• ✅ Consistent naming across projects
• ✅ Helps users learn slice naming conventions
• ✅ Reduces typos
• ✅ Still allows custom names

UI Mockup (Concept)

Current Slice: [031-slice.hero-section ▼]
               └─ Dropdown shows:
                  • 100-slice.foundation
                  • 200-slice.core-features
                  • 900-slice.maintenance
                  • ─────────────────────
                  • Recently used:
                  • 050-slice.auth
                  • 031-slice.hero-section

Auto-fill Integration

This would work seamlessly with the existing auto-fill feature (#18) - selecting a slice from dropdown would still auto-populate the task file field.

Priority

Medium - Nice quality-of-life improvement, not blocking
