📝 Walkthrough

Walkthrough

This PR adds comprehensive documentation for the mock adapter, a hand-written test utility that provides in-memory adapter behavior without real PostgreSQL connections. The new guide covers instantiation, response queueing, permission handling, and distinguishes it from the generated mockgen package, with cross-links from the development guide and table of contents.

Changes

Mock Adapter Documentation

Layer / File(s)	Summary
Mock Adapter Overview and Setup get-prest/mock-adapter.md	Introduces the mock adapter package and documents how to create it with mock.New(t), assign it to config.PrestConf.Adapter, and how the embedded database/sql driver registration enables transaction helper paths without network access.
Mock Adapter Operations, Permissions, and Patterns get-prest/mock-adapter.md	Describes queued-response consumption and test failure when operations exceed available items, details permission behavior via TablePermissions reading config.PrestConf.AccessConf, and explains the hand-written controller-style approach vs. the generated mockgen package for strict expectations.
Cross-Document References and Table of Contents get-prest/development-guide.md, SUMMARY.md	Adds guidance in the development guide directing tests that don't require PostgreSQL to use the mock adapter, and includes a TOC entry linking to the new documentation.

🐰 A mock adapter hops into view,
In-memory tests now ring true!

Permissions flow, and tests take flight! ✨

- Line 10: The "Basic usage" heading is currently H3 (### Basic usage) which
skips H2 and breaks document structure; change that heading to H2 (## Basic
