* Normalize session_id into ws_id as sole persistent identity Eliminate the separate session_id concept. The workstream ID (ws_id) is now the single identity used for both real-time routing and conversation persistence, removing a layer of indirection that was 1:1 in practice and buggy on resume (stale pointers, orphaned rows). Schema changes (migration 006): - Drop sessions table; add alias/title columns to workstreams - Rename conversations.session_id → ws_id - Rename session_config table → workstream_config (ws_id column) - Data migration remaps existing conversations to ws_id Storage/API renames: - register_session → register_workstream (already existed, merged) - save_message/load_messages now keyed by ws_id - resolve_session → resolve_workstream - ChatSession.session_id property → ws_id - ChatSession.resume_session() → resume() - resume_session field → resume_ws - SessionResumedEvent → WorkstreamResumedEvent - /api/sessions → /api/workstreams/saved - /sessions slash command → /workstreams - --session-retention-days → --retention-days Channel eviction recovery simplified: reuses old ws_id directly instead of get_session_id_by_ws() reverse lookup. * Fix Copilot review feedback: stale session wording in docs, regenerate OpenAPI spec - docs/channels.md: "resumes the session" → "resumes the workstream", "Session resumed:" → "Resumed:", "old session was pruned" → "old workstream was pruned" - docs/api-reference.md: "Each session object" → "Each saved workstream object", field descriptions updated, removed stale node_id field - sdk/typescript/openapi-server.json: fully regenerated from Python models — removes all stale session_id properties from WorkstreamInfo, DashboardWorkstream, CreateWorkstreamResponse schemas
