Documentation for SDD 2.0 clarifying the Git integration and providing workflow examples for requirement changes at different stages

[AndreyMalykhin]

Hey guys, I couldn’t find in the docs whether (or when) you need to use Git and commit changes in order to use the --refine argument for both plan and implement. SKILL.md mentions using a Git diff, though.

It’d also be great to document:

• more real-world scenarios for what to do when requirements change at different stages (e.g., after /implement).
• whether you need to clear context (e.g., Claude Code /clear) before running /plan or /implement.
• whether you need to use /plan or /implement again after the conversation compaction process (e.g. Claude Code /compact).
• whether every prompt in a conversation needs to be prefixed with /plan or /implement. For example:
  /add-task -> /plan -> /implement -> /implement I've changed my mind -> /implement I've changed my mind again
  vs
  /add-task -> /plan -> /implement -> I've changed my mind -> I've changed my mind again
