feat: add Mythos security remediation slide deck

[devin-ai-integration]

Summary

Adds a self-contained HTML slide deck (reveal.js via CDN) covering the Mythos threat landscape and its implications for security remediation operationalization.

Presentation covers:

• What Mythos is: Project Glasswing, Claude Mythos Preview capabilities, the Firefox 150 proof point
• What Mythos is NOT: not available today, not the only answer, not a reason to wait
• The hype check: 271 findings ≠ 271 critical CVEs (SecurityWeek analysis)
• The containment problem: Bloomberg unauthorized access timeline
• The bottleneck shift: from "find the bug" to "fix it fast enough"
• Five new pressures on engineering teams
• The remediation pipeline and what can be automated
• Where Devin fits as a remediation throughput engine (not a scanner)
• Devin + security stack integration (Snyk, OWASP, security scan automations)
• The right operational model with engineering controls
• Five actionable steps teams should take now

Technical details:

• Single HTML file, no build step required — open in any browser
• Uses reveal.js 5.1.0 from CDN with custom dark theme
• Responsive grid layouts, animated fragments, timeline visualizations
• All sources cited with hyperlinks (Anthropic, Mozilla, SecurityWeek, Bloomberg, Snyk, Devin Docs)
• PDF export supported via reveal.js print stylesheet

Review & Testing Checklist for Human

• Open presentations/mythos-security-remediation.html in a browser and click through all 19 slides — verify content accuracy against cited sources
• Verify the "What Mythos IS / IS NOT" slide correctly frames the nuance (near-term risk, not today risk; forcing function, not the fix itself)
• Check that no customer names or identifying information appear in the deck

Notes

• The deck is designed for facilitator-led delivery with progressive fragment reveals
• All external links use publicly available sources — no gated content
• File placed in presentations/ directory (new directory for this repo)
