chore(deps): upgrade TypeScript 5.9.3 → 6.0.3 (explicit dep)

[xdanger]

Summary

• Adds typescript as an explicit devDependency at ^6.0.0 (resolves to 6.0.3)
• Previously TypeScript was auto-installed as a peer dependency of typescript-eslint at 5.9.3
• All other direct dependencies were already at their latest stable versions (confirmed via pnpm outdated + npm show)

Breaking-change risk

Low. TypeScript 6.0 removes some deprecated APIs and tightens checks, but:

• typescript-eslint@8.59.3 explicitly supports >=4.8.4 <6.1.0, so 6.0.3 is within range
• No src/ directory exists yet — no TypeScript source to re-check
• pnpm audit reports no vulnerabilities

Test plan

• pnpm install resolves cleanly with TypeScript 6.0.3
• pnpm lint passes (ESLint + Prettier checks green)
