feat: rebrand OpenClaw references to Hermes during migration

- Add rebrand_text() that replaces OpenClaw, Open Claw, Open-Claw,
  ClawdBot, and MoltBot with Hermes (case-insensitive, word-boundary)
- Apply rebranding to memory entries (MEMORY.md, USER.md, daily memory)
- Apply rebranding to SOUL.md and workspace instructions via new
  transform parameter on copy_file()
- Fix moldbot -> moltbot typo across codebase (claw.py, migration
  script, docs, tests)
- Add unit tests for rebrand_text and integration tests for memory
  and soul migration rebranding
