Create jayson branch with automated setup tooling

[Copilot]

Creates the jayson branch locally and provides tooling to push it and set it as the default branch. Repository admin access required to complete.

Changes

• Branch creation: jayson branch created locally with current repository state
• Automated script (create_jayson_branch.sh): Validates repository state, checks commit/remote existence, pushes branch with error handling
• Documentation (CREATE_JAYSON_BRANCH.md): Instructions for Web UI, GitHub CLI, and API methods to change default branch
• Reference tracking (.jayson-branch-ref): Commit SHA for script validation

Next Steps

Repository admin must complete:

# 1. Push the branch
./create_jayson_branch.sh

# 2. Change default branch at:
# https://github.com/JaysonKhan/Telegram/settings/branches

The jayson branch contains identical code to current state plus the setup tooling.

Original prompt

create another branch and change default branch it. branch name is jayson
