feat: portfolio architecture v2

[UAJOP]

Why

The portfolio has grown from a static personal site into a product with Recruiter Mode, Ajoop, Command Palette, bilingual content, case studies, games, request intake, automated QA and active flagship products. Current project truth had started drifting across HTML, the monolithic runtime and the old flagship-copy.js patch layer.

Architecture V2

• adds portfolio-data.js as the source of truth for current flagship projects, recruiter profiles, build status, Labs and sanitized SINAMA evidence examples
• adds portfolio-v2.js for Recruiter Mode V2, role deep links, evidence-backed Ajoop synchronization, unified V2 bilingual copy, Build Log, Labs, request receipts and SINAMA Evidence Explorer
• adds portfolio-v2.css for the new runtime surfaces
• retires flagship-copy.js
• preserves the previous monolithic runtime byte-for-byte as legacy-script.js
• converts script.js into a compatibility bootloader:
  • migrated pages: registry → bootloader → legacy runtime → explicit V2 runtime
  • legacy pages: bootloader automatically injects registry → legacy runtime → V2 runtime and V2 CSS
• this makes current Recruiter Mode / Ajoop evidence global across older case studies, certificates, 404 and mini-game pages without risky all-at-once HTML rewrites
• documents the migration and source-of-truth rules in PORTFOLIO_ARCHITECTURE.md

Product / UX changes

• simplifies the homepage around SINAMA + Merge Rush, role evidence, experience and current build status
• removes tutorial-scale Calculator / Weather proof and the old AI workflow / 3D experiment sections from the homepage
• adds role-specific recruiter URLs:
  • ?role=applied-ai
  • ?role=solution-engineering
  • ?role=software
  • ?role=game
• upgrades Recruiter Mode to selectable role-specific evidence profiles
• grounds current Ajoop answers in the central evidence registry; Ajoop remains deterministic and does not claim a live LLM/RAG backend in this release
• adds now.html living Build Log
• adds labs.html so technical experiments no longer dilute the professional project narrative
• removes the stale Interview Run concept from the active game catalog
• restructures Works around flagship evidence → supporting evidence → archive/Labs policy
• aligns About and Experience with Applied AI / AI Solutions / Solution Engineering direction

SINAMA Interactive Proof

• adds a sanitized static Evidence Explorer:
  Conversation → Tool Trace → Deterministic Findings → Release Verdict
• lets visitors compare a healthy READY run with a premature-side-effect BLOCKED run
• keeps Semantic Judge explicitly labeled as develop/integration-only and advisory
• does not pretend the static portfolio explorer is a live evaluator

Merge Rush Proof

• strengthens the case study around implemented gameplay and production architecture
• documents multi-cell occupancy, preview-before-commit, deadlock-aware logic, Endless repair loop, progression and platform abstractions
• surfaces verified development QA states for wide / portrait / landscape / square / combo / game-over views
• keeps the private development repository private
• does not fabricate gameplay screenshots: the private QA record references screenshots, but the binaries are not committed in the accessible branch; real approved screenshots/video can be added later

Request flow

• preserves the Apps Script + Google Forms + email fallback path
• explicitly states that no-cors browser submission cannot truthfully prove server-side receipt
• adds a browser submission reference while clearly labeling it as not a server confirmation

Drift prevention / QA

• adds JavaScript syntax validation for every root JS file
• adds qa-portfolio-consistency.js and npm run qa:portfolio
• guard verifies registry projects, recruiter profiles, evidence states, retired files, global bootloader coverage, homepage hierarchy, game catalog policy, sitemap policy and request/Ajoop architecture truth
• adds Labs + Build Log to Pa11y and Lighthouse
• adds legacy single-work.html to Lighthouse specifically to verify the global bootloader path
