fix(macOS): rename Clawdbot directories to Moltbot for naming consistency

Directory renames:
- apps/macos/Sources/Clawdbot → Moltbot
- apps/macos/Sources/ClawdbotDiscovery → MoltbotDiscovery
- apps/macos/Sources/ClawdbotIPC → MoltbotIPC
- apps/macos/Sources/ClawdbotMacCLI → MoltbotMacCLI
- apps/macos/Sources/ClawdbotProtocol → MoltbotProtocol
- apps/macos/Tests/ClawdbotIPCTests → MoltbotIPCTests
- apps/shared/ClawdbotKit → MoltbotKit
- apps/shared/MoltbotKit/Sources/Clawdbot* → Moltbot*
- apps/shared/MoltbotKit/Tests/ClawdbotKitTests → MoltbotKitTests

Resource renames:
- Clawdbot.icns → Moltbot.icns

Code fixes:
- Update Package.swift paths to reference Moltbot* directories
- Fix clawdbot* → moltbot* symbol references in Swift code:
  - clawdbotManagedPaths → moltbotManagedPaths
  - clawdbotExecutable → moltbotExecutable
  - clawdbotCommand → moltbotCommand
  - clawdbotNodeCommand → moltbotNodeCommand
  - clawdbotOAuthDirEnv → moltbotOAuthDirEnv
  - clawdbotSelectSettingsTab → moltbotSelectSettingsTab
