dsh-session-tree v0.1.0-beta.1

Added

• Initial public beta of the Git-like session tree for DeepSeek Harness.
• Immutable branching from loaded, completed turn/end checkpoints through the
  native DSH session fork API.
• Lineage visualization for root sessions, forks, and subagents, with fail-soft
  handling of orphaned, duplicate, or cyclic records.
• Bounded rendering, history pagination, and an in-view mutex that prevents
  accidental duplicate fork submissions.
• Chinese and English user interfaces, safety notices, documentation, tests,
  build verification, and distributable DSH plugin artifacts.

Security

• Conversation branching never claims to roll back files, commands, processes,
  network requests, or other external side effects.
• Ambiguous or partially successful fork requests are not retried automatically.
