v0.3.0 — merged git-style lineage graph, injected-message split, Harness 0.1.5-rc.2

Changed

• The WebUI Session Tree now merges every non-subagent Session in the current
  lineage into one git-style graph. Native fork/clone prefixes are deduplicated
  by both nodeId and sessionEventSeq; branch-specific nodes keep
  session-qualified identities. Fork points carry main/fork/clone badges, the
  open Session's path is highlighted, Session branches and node subtrees can
  collapse independently, and clicking another Session's node opens that
  Session before jumping. Tree loading fans out after an 80 ms debounce and
  isolates per-Session failures behind placeholders. The previous separate
  right-panel branch summary is absorbed into this graph.
• Session-tree user messages now separate typed human prompts from
  harness-injected context (skill catalog prompts, system-prompt snapshots,
  context notices). Injected user/message events are still projected into the
  append-only tree — jump/fork re-select the model-visible surface from the
  tree path, so dropping them would strip skill and runtime context from later
  model turns — but they carry metadata.injected and are hidden from every
  user-facing surface: the /tree panel, the /fork prompt selector, the
  /fork userNodeCount, and the previous-prompt fork-menu title. Producer
  source.kind drives the split ('user' is typed input; 'plugin',
  'skill-catalog', and other kinds are injected); legacy string or missing
  sources stay presented as human input. The sidecar format version bumped
  1 → 2 so cached trees built before the marker re-project from the native
  Session log.
• The /tree panel row preview expands on click (toggling the complete node
  message in a bounded scroll area) instead of on hover; the native hover
  title tooltip on the summary was removed and the row-count stat now counts
  only displayed (non-injected) nodes.
• The packages now target DeepSeek-Harness 0.1.5-rc.2: the tree-restore
  cursor is written as a real system/message surface event, which needs the
  surface semantics introduced in the 0.1.5 line. The @deepseek-ai/* peer
  ranges moved from ^0.1.2-alpha.3 to ^0.1.5-rc.2 accordingly.

Fixed

• The /fork prompt selector lists every typed prompt again instead of only
  the tree root. Prompts-only mode re-parents each user message to its nearest
  displayed prompt, so a prompt whose assistant/tool ancestor is filtered out
  no longer becomes unreachable in the row graph.
