brand: rename agent brain files from picoclaw to aldo

Update workspace template files that form the agent's identity:
- SOUL.md: "I am aldo" (was "I am picoclaw")
- IDENTITY.md: simplified to "Aldo" with minimal description
  (was 56 lines of picoclaw branding, now 7 lines - saves ~1K tokens)
- hardware skill reference: updated binary name
