Fixes a false configured: false from the get_setup_status MCP tool when the server runs in legacy inline mode (the launch shape the Claude Code plugin UI uses: --host/--user/--dbname + REDSHIFT_PASSWORD env). The status tool now detects inline mode and adds a source: "inline" | "profile" field so agents can tell which config mechanism is live. The password value is never materialized in the response (presence-only bool).

See #39.

Pre-release: triggers TestPyPI smoke test. PyPI-live promotion follows after the dry-run goes green.
