fix(sessions): replace z.unknown() with typed sessionOutput schema

[Ysh204]

Summary

Currently, sessionsListOutput defines session records as z.array(z.unknown()), so the generated schema exposed through --schema does not describe the structure of session objects.

This PR introduces a strongly typed sessionOutput Zod schema matching the objects returned by sessionItem() in src/commands/sessions.ts.

Changes

• Add a typed sessionOutput schema covering:

  • channel_id
  • network
  • origin
  • symbol
  • deposit
  • spent
  • remaining
  • status
  • remaining_secs
  • created_at
  • last_used_at

• Replace z.array(z.unknown()) with z.array(sessionOutput) in sessionsListOutput

• Add a regression test verifying the generated schema exposes the expected session properties
