Adds a new security-focused tutorial that demonstrates creating a PreToolUse hook to block .env access, adds a Codebase Documenter tutorial for generating developer docs with a custom agent, and includes related tutorial images. Also updates the Codebase-Documenter template link in the documentation to point to the GitHub agent library.
Files added:
enhance-security-with-hooks.md — new tutorial explaining Hooks, PreToolUse flow, and a PowerShell example to block .env access.
fix-documentation-gaps-using-custom-agent.md — new/updated tutorial for the Codebase Documenter agent (includes walkthrough, examples, and workflow guidance).
code-studio/tutorials/tutorials-images/... — new tutorial images (e.g., enhance-security-with-hooks-blocked-env-access.png and others).

Why: These additions provide clear guidance for teams to:
Protect secrets and enforce safe tool use with Hooks.
Automate generation and maintenance of developer documentation using a custom agent.
Improve onboarding and security best practices for Code Studio users.
