Toolkit MCP routes fail with SQLite owner lock in local daemon #1618

Executor version

1.5.40. The same code path is present on 1.5.41.

Reproduction

1. Start the local headless daemon with at least one toolkit configured.
2. Initialize the default /mcp endpoint. It succeeds.
3. Send the same MCP initialize request to /mcp/toolkits/<slug>.

Expected

The toolkit-scoped MCP session initializes successfully.

Actual

The toolkit route returns HTTP 500 and the daemon logs:

Failed to open local SQLite data. Close other Executor processes and retry, or run with --log-level debug for details.

Only one Executor process is running. That process already owns the data-directory lock. createConfigForResource calls createExecutorHandle for the toolkit, which attempts to acquire the same local SQLite ownership lock a second time inside the daemon.

Proposed fix

Reuse the shared daemon database when constructing a toolkit-scoped executor, while retaining the toolkit-specific plugin configuration. A regression test should initialize a toolkit MCP route in the same server process.
