🛡️ Add CRITICAL Broken Auth vulnerability to SECURITY_ISSUE.md

[Vaiditya2207]

I have successfully completed the security audit as Sentinel.

1. Vulnerability Found: I discovered a CRITICAL Broken Authentication vulnerability in the Aether upload_handler (syscore/src/server/aether.rs). The handler uses unwrap_or_else on the AETHER_UPLOAD_KEY environment variable, defaulting to a weak static key "update_me_please" if not present. This allows unauthenticated attackers to bypass authentication and upload files.
2. Documentation Update: I appended a detailed, professionally formatted GitHub Issue to SECURITY_ISSUE.md describing the vulnerability, its impact (potential unauthenticated RCE when combined with the file write vulnerability), steps to reproduce, and recommended remediation. I was careful to append to the file to preserve the existing Arbitrary File Write report.
3. Journal Entry: I updated .jules/sentinel.md with an architectural learning about the systemic cause of this pattern (using weak defaults for missing environment variables intended for developer convenience).
4. Verification: I verified the contents of both files using cat and successfully ran the test suites (cargo test and bun test) to ensure no code was broken, satisfying the completeness rule. As instructed for the Sentinel role, I did not modify the source code to fix the vulnerability.

Poem

I hopped through notes with twitchy nose,
Found brittle keys and path-trail woes.
A carrot-safe fix glows bright tonight,
While auditors nibble bugs from sight.

Improve remediation to recommend startup-time validation.

The current suggestion to use expect inside the request handler will cause a runtime panic on the first upload request if the environment variable is missing. This defers failure to request time rather than startup time.

Update the remediation to recommend loading AETHER_UPLOAD_KEY at application startup and failing immediately if it's absent. This ensures the service never starts in an insecure configuration.

For example:

// At application startup (e.g., in main or a config loader)
let aether_upload_key = std::env::var("AETHER_UPLOAD_KEY")
    .expect("FATAL: AETHER_UPLOAD_KEY environment variable is missing.");

// In the handler, use the pre-loaded key
if auth_header != Some(&aether_upload_key) { ... }
