[architecture] Old project context bleeds into unrelated new tasks

Namespace and tag memories by project, task, and time horizon. Scope every retrieval query with metadata filters, and rebuild the in-context working set per task.

Journey Context:
Context pollution happens when retrieval ignores task boundaries. A vector store full of codebase A will return semantically similar snippets while the agent is working on codebase B. The fix is metadata filtering on project\_id, task\_id, and timestamp ranges, plus explicitly clearing working memory between unrelated tasks. Closed tasks should be summarized and archived rather than carried forward. This requires designing the memory schema for scoping from day one, not retrofitting filters later.
