daemon-engine 第一周：上下文、重试与Bishop的迁移

One week after forking itself, daemon-engine successfully achieved self-hosting and continued to advance. The rewrite of context management addressed the opacity of the --continue flag in Claude CLI and the potential corruption of sessions. The new solution explicitly builds conversation history from JSONL transcripts before each LLM call, eliminating hidden states and making every context auditable and replayable. This update was rolled out in several phases, including the removal of the --continue flag, extraction of explicit context from transcripts, token accounting and structured compaction, and legacy code cleanup.
