feat(openclaw-plugin 2.0): from memory plugin to context engine

[Mijamind719]

…ntext engine

1. Rename the OpenClaw plugin from memory-openviking to openclaw-context-plugin and switch its kind from memory to context-engine.
2. Keep auto-recall and ingest-reply-assist on before_prompt_build to preserve the existing prompt injection behavior.
3. Move the canonical auto-capture flow from the old agent_end-style lifecycle to ContextEngine afterTurn.
4. Delegate compact handling to the legacy compact engine when it is available, so existing compaction behavior can still be reused.
5. Preserve the OpenViking tools and local process management while updating setup helpers, installers, docs, and OpenClaw config paths to plugins.slots.contextEngine.

发现了一些命名一致性问题 (non-blocking suggestions):

文档中的旧插件名称引用

examples/openclaw-plugin/INSTALL-ZH.md (行 211, 215)

• 文档中仍使用旧插件名称 "memory-openviking",应更新为 "openviking"
• 第 211 行描述和第 215 行 grep 命令中都需要更新

建议改为:

grep -i inject /tmp/openclaw/openclaw-2026-03-13.log | awk -F'"' '{for(i=1;i<=NF;i++) if($i ~ /^[0-9]{2}:[0-9]{2}:[0-9]{2}/) {time=$i; break}} /injecting [0-9]+ memories/ {print time, "openviking:", gensub(/.*(injecting [0-9]+ memories).*/, "\\1", "1")}'

代码中的旧插件名称引用

examples/openclaw-plugin/process-manager.ts:175

• 错误消息: memory-openviking: port ${port} is occupied...
• 建议改为: openviking: port ${port} is occupied...
