v0.11.5

Added

• Fork context preamble: tasks run with context: "fork" are now wrapped with a default preamble that anchors the subagent to its task, preventing it from continuing the parent conversation.
• Prompt-template delegation bridge (prompt-template-bridge.ts) on the shared extension event bus with request/started/response/update events, cwd safety checks, and race-safe cancellation.
• Delegated progress streaming via prompt-template:subagent:update.

Changed

• Session lifecycle reset now preserves the latest extension context for event-bus delegated runs.
• [fork] badge shown only on result row, no longer duplicated on tool-call row.
