docs(security): Report weak default credential vulnerability in Aether upload

[Vaiditya2207]

Acted as Sentinel to document a CRITICAL security vulnerability without modifying code.

Findings:

• Discovered a weak default credential fallback (unwrap_or_else(|_| "update_me_please".to_string())) in syscore/src/server/aether.rs during file upload authorization check.

Actions:

• Created a new journal entry in .jules/sentinel.md documenting the systemic pattern.
• Appended a formatted GitHub issue report to SECURITY_ISSUE.md detailing the vulnerability, impact, reproduction steps, and remediation.

Verification:

• Ran cargo test in syscore to ensure no breakages.
• Pre-commit code review passed.

📝 Walkthrough

Walkthrough

This PR documents a critical broken authentication vulnerability in the Aether upload handler where missing AETHER_UPLOAD_KEY environment variable falls back to hardcoded weak default credentials. Both the sentinel registry and detailed security issue document are updated to record the vulnerability, reproduction steps, and secure remediation approach.

Changes

Aether weak credential vulnerability documentation

Layer / File(s)	Summary
Weak Aether upload credentials documentation .jules/sentinel.md, SECURITY_ISSUE.md	Sentinel registry entry and comprehensive security issue documentation are added together to record the broken authentication vulnerability in upload_handler, including auditor guidance to fail securely when AETHER_UPLOAD_KEY is unset, reproduction steps, and OWASP + CWE references.
