Refactor info command into separate functions and add usage statistics

[sestinj]

Summary by cubic

Refactored the CLI info command into smaller functions and added session usage stats (cost and token counts) to the output. Improves maintainability and gives users clear visibility into session usage.

• New Features

  • Display total cost, input/output tokens, and cache read/write tokens.
  • Show "No usage data yet" when unavailable and warn on errors.

• Refactors

  • Extracted info builders: getVersionInfo, getAuthInfo, getConfigInfo, getSessionInfo, getUsageInfo, getDiagnosticInfo; composed in handleInfoSlashCommand.
  • Reduced inline logic and separated concerns for clearer, testable code.

^{Written for commit 30b8d5c. Summary will update on new commits.}
