feat: v3.17.0 — wire NpgsqlRest.Mcp into the standalone client

vbilopav · vbilopav · commit 35fb6e308047 · 2026-06-08T16:12:12.000+02:00
NpgsqlRestClient now references the Mcp plugin and registers it from a McpOptions
config section in CreateCodeGenHandlers (Enabled / UrlPath / ServerName /
ServerVersion / Instructions). Disabled by default — when McpOptions:Enabled is
not true the server is not registered (no behavior change). Full suite green (2160).

Discoverability (appsettings/ConfigTemplate/ConfigDefaults/schema McpOptions section)
and docs follow in a separate change.
