fix: preserve parallel connector runs and state

[Gautam Sharma (GautamSharma99)]

Summary

Fixes #542.

Connector run IDs previously used only an ISO timestamp, so calls in the same millisecond shared raw-data directories and fixed filenames. MCP operations also read connector state before network work and later replaced the whole document from that stale snapshot, dropping parallel run history.

Changes

• Add a UUID suffix to every connector run ID while retaining the sortable timestamp prefix.
• Add updateConnectorState, a process-local FIFO transaction per connector that re-reads state immediately before applying an updater and committing it.
• Move MCP discovery and tool-call run recording to the atomic update API, so parallel operations preserve both run summaries and cursor/state fields.
• Write connector state and raw JSON through unique same-directory temporary files followed by atomic rename, avoiding partial files and temp-path collisions.
• Add regression coverage for distinct run IDs and deterministic concurrent state transactions, asserting both runs survive in state.json.
• Add a patch changeset.

Why this fixes the race

Each invocation now owns a unique raw directory, so mcp-tools.json and mcp-tool-result.json cannot replace evidence from another invocation. MCP state commits are serialized per connector and each queued commit reads the latest file, so a later completion merges with the prior run instead of writing an old snapshot over it. Atomic replacement preserves the existing file until the new JSON is complete.
