🛡️ Sentinel: [MEDIUM] Add ReadHeaderTimeout to http.Server

[euxaristia]

🚨 Severity: MEDIUM
💡 Vulnerability: Multiple http.Server instances were found without a configured ReadHeaderTimeout. This is flagged by gosec as G112 and is a known vector for Slowloris (CWE-400) vulnerabilities.
🎯 Impact: An attacker could exhaust server resources by opening connections and sending HTTP request headers exceedingly slowly, potentially leading to a Denial of Service (DoS) for the affected endpoints.
🔧 Fix: Added ReadHeaderTimeout: 10 * time.Second to all http.Server initializations (internal/mcp/oauth.go, internal/oauth/loopback.go, internal/provideroauth/openrouter.go, internal/tools/bash_tool_test.go).
✅ Verification: Verified by re-running the test suite (make test), linting (make lint), and confirming the absence of G112 warnings using gosec.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 30 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
