[BUG] Project Name Case Inconsistency

[jrand0m]

Bug Description 🐛
Project names are normalized to lowercase when removing but accepted as-is when adding, creating confusion about actual project name.

Steps To Reproduce

1. Install basic-memory via uv
2. Run bm project add Life /path/to/vault
3. Observe success message shows 'Life'
4. Run bm project remove Life
5. Observe success message shows 'life' (lowercase)

Expected Behavior

• Project name case should be consistent across all operations
• Either normalize on add (show "life added") or respect case on remove (show "Life removed")
• User should see same capitalization they provided

Actual Behavior

• Add operation: Project 'Life' added successfully
• Remove operation: Project 'life' removed successfully
• Case mismatch causes confusion about actual stored project name

Environment

• OS: macOS
• Python version: 3.11.3
• Basic Memory version: [0.16.2]
• Installation method: uv
• Client: Claude Desktop / MCP

Impact ⚠️
Low severity, but affects user confidence in command accuracy
