rayhpeng 85a591751a docs(schedule): record the launcher and version contracts
The walkthrough still described the `UNSET` sentinel and a two-error
launcher, and said nothing about the optimistic token. Brings both
documents up to what the code now does:

- partial updates use plain `None`, with the condition that makes that
  safe stated explicitly so a future nullable field does not quietly
  break it
- the launcher's third escape and why the failed/indeterminate line is
  the #4452 guard rather than a taxonomy preference
- what `version` is for, why `save` is a conditional UPDATE rather than
  read-check-write, and that it is the slice's one schema change

Getting Started

  1. New to DeerFlow? Start with SETUP.md for quick installation
  2. Configuring the system? See CONFIGURATION.md
  3. Understanding the architecture? Read ARCHITECTURE.md
  4. Building integrations? Check API.md for API reference
  5. Wondering why the layers are split the way they are? Read HEXAGONAL_ARCHITECTURE_zh.md for the rules, then SCHEDULE_DESIGN_zh.md for a worked example
