docs: identify interns in task branch names

[vicky-dot20]

Task ID

Framework maintenance (fresh-intern simulation finding)

Issue

Closes #1

Summary

Adds the intern's GitHub username to every prescribed task branch so branch ownership is visible and parallel attempts do not collide.

Implementation

• Uses ask//- across all 206 task specifications.
• Updates onboarding, development workflow, authoring guidance, and the reusable task template.
• Extends validation so future tasks must preserve the convention.

Testing

pm run validate — passed for 206 tasks.

• Searched curriculum and guides for old username-less task branch patterns — none remain.
• git diff --check — passed.

Edge Cases

The placeholder remains generic in framework content; onboarding tells each intern to replace it with their exact GitHub username.

Documentation

Updated onboarding and shared workflow/authoring documentation.

AI Usage

• AI used: Yes
• Tools used: OpenAI Codex
• Purpose: Implement and verify the repository-wide documentation improvement.
• What AI helped with: Consistent mechanical update, validation, and workflow testing.
• What I personally implemented: The user identified the branch-ownership problem and approved the proposed convention.
• What I changed from AI output: The convention was selected from the user's requirement and verified against the actual multi-account workflow.
• How I verified the result: Repository validation, pattern search, diff check, and fork push.
• Can I explain this implementation? Yes

Self Review

• Requirements satisfied
• Tests pass
• Code formatted
• No unnecessary changes
• No secrets committed
• Documentation updated
• I understand the submitted change

Screenshots / Evidence

Direct upstream push from �icky-dot20 returned HTTP 403 as expected. The same commit pushed successfully to the intern fork.

Notes for Reviewer

This is the first improvement found through the fresh-intern simulation.

[vkverse]

The onboarding branch command uses inside a Bash code block. Angle brackets are shell redirection syntax, so a fresh intern who copy-pastes the command can get a syntax error. Please use a copy-safe example such as task/octocat/ori-001-software-development, then explicitly tell the intern to replace octocat with their GitHub username. Keep the generic placeholder in non-command task specifications if useful, and rerun validation.

[vicky-dot20]

Addressed the requested change in commit: the Bash example now uses task/octocat/..., and the text explicitly tells interns to replace octocat with their GitHub username. npm run validate and git diff --check pass.

[vkverse]

The requested copy-safety issue is resolved: the runnable Bash example now uses octocat, and the following instruction clearly tells interns to replace it with their GitHub username. Validation passes. Approved.
