v1.5.3 - README recruiter/CTO reorder + record-clips sync

What's Changed

README.md - Optimized for Recruiters & CTOs

Reordered sections to follow the "What -> Wow -> How -> Proof" pattern:

• Features table now comes before screenshots - readers understand why before seeing what
• • Architecture diagram moved early for CTOs who jump to system design first
• • Demo screenshots follow after the hook is set (collapsed
    )
• • Testing / 100% coverage moved before Quick Start as social proof
• • Reference sections (Dev Commands, Env Vars, Observability) pushed to the bottom

scripts/record-clips.mjs - Synced with capture-screenshots.mjs

• Added clearCache(), resetDashboard(), clickPreset(), clickEdgeCase(), waitForHitlModal() helpers
• • All ticket clips now use clickPreset(page, label) - no more manual typing
• • Edge case clips use clickEdgeCase() (auto-switches to Edge Cases tab)
• • history clip pre-populates 5 tickets before recording
• • database clip uses text=DATABASE locator + scroll-back after table expand
• • Removed legacy humanType, typeAndSubmit, inline EDGE_MSG strings
