fix(deps): move type-fest from devDependencies to dependencies

[knsv]

Summary

Resolves #6629

• Moved type-fest from devDependencies to dependencies in packages/mermaid/package.json

type-fest types (SetRequired, SetOptional, RequiredDeep, Entries) are used in 5 source files whose declarations are published in the dist/ .d.ts files. With type-fest only in devDependencies, consumers get TS2307: Cannot find module 'type-fest' errors when type-fest is not available transitively — which happens when packages like globals (v14+) drop their own type-fest dependency.

Classification

• Change type: Dependency/packaging fix
• Breaking change: No
• Shared code touched: No (only package.json manifest)

Verification

• Lint: passed
• Build: passed (pnpm build:mermaid)
• Dependency check: type-fest in dependencies, not in devDependencies
• Changeset: generated (patch)
• TDD: N/A — packaging fix, no code logic changed
• Visual spot-check: N/A — no rendering changes
• Full e2e: not run — no code changes
