🐛 fix(security): close audit findings for v0.7.0

[scttbnsn]

Summary

• close PW-SEC-001 through PW-SEC-010 with fail-closed auth, versioned full-target Ed25519 signatures, bounded expensive work, descriptor/root-confined file handling, strict TLS pairing, and accurate audit claims
• ship generated CSP and browser security headers for every exported website/docs route
• align from-source Docker builders with Go 1.26.5 and eliminate the weekly High-severity container finding
• cut the v0.7.0 changelog, compatibility contract, supported-version policy, docs, website, FAQ, and roadmap in the established operator-first voice

Verification

• gofmt, go vet, go build, go test -race
• golangci-lint, govulncheck, gosec
• six fuzz smoke targets and integration-suite compilation
• npm/TypeScript lint, npm audit, static docs+website production build, CSP header tests
• actionlint, zizmor, staged gitleaks
• GoReleaser check and full snapshot archive build
• no-cache Docker build plus Grype: no vulnerabilities found

Warning

Review limit reached

@scttbnsn, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 54 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.
