Add reference table of available Feature Flags to Developer Guide

[vishal2005025]

Summary

The Handbook currently references the feature flags used in Jitsi Meet by linking to the source file. While helpful, SDK developers must navigate into the repository to discover available flags and their behavior.

To improve developer experience, the Handbook should include a reference list of exported feature flags directly in the Developer Guide. This would provide quick visibility into configurable behavior when embedding the SDK.

Proposal

Add a table to the Feature Flags section of the Developer Guide that includes:

• Flag key name
• Default value (when available)
• Short description based on existing comments or documentation in the source

Include a note that flags may change over time and that the Jitsi Meet source remains the authoritative reference.
