[Architecture] Refactor Achievement Calculator to Support Retroactive Audits (Module #33)

[Darkvader-ship-it]

Estimated Effort: 2 weeks / 8 days

Impacted Subsystems / Files:

• app/api/achievements/route.ts
• lib/achievement-store.ts
• components/profile-panel.tsx

Context & Problem Statement:
In app/api/achievements/route.ts and associated files lib/achievement-store.ts, Historical achievement progress is lost if events fail to trigger. Addressing this issue is required to harden system stability, optimize execution speed, and eliminate technical debt across the dApp codebase.

Technical Requirements & Scope:

1. Audit execution flow in app/api/achievements/route.ts.
2. Implement isolated domain module in lib/achievement-store.ts.
3. Add error boundaries and type-safe schema validation.
4. Write comprehensive automated unit test suite.

Multi-File Change Surface:
Directly alters code logic in app/api/achievements/route.ts, lib/achievement-store.ts, and UI wiring in components/profile-panel.tsx.

Acceptance Criteria:

• System execution passes performance benchmarks.
• Zero unhandled exception tracebacks in production logs.
• Full unit test pass rate.

Suggested Approach / Investigation Steps:

1. Benchmark target baseline metrics.
2. Implement domain code refactoring.
3. Verify changes end-to-end.
