fix!: replace deprecated getDefaultClaudePath with getClaudePaths

BREAKING CHANGE: getDefaultClaudePath() has been replaced with
getClaudePaths() which returns an array of paths.

- Replace getDefaultClaudePath with getClaudePaths in mcp.ts

- Replace getDefaultClaudePath with getClaudePaths in commands/mcp.ts

- Replace getDefaultClaudePath with getClaudePaths in blocks.ts

- Replace getDefaultClaudePath with getClaudePaths in debug.ts

- Add proper error handling for empty path arrays
