perf: speed up monorepo linting and formatting

[aXenDeveloper]

Summary

• stop running Prettier through eslint-plugin-prettier in every ESLint process
• keep eslint-config-prettier/flat so ESLint rules do not conflict with Prettier
• cache ESLint results per workspace using content hashing and enable ESLint worker concurrency
• cache Prettier's explicit formatting commands
• cache only the read-only lint Turbo task; leave lint:fix uncached because it mutates source files
• apply the same scripts and Turbo configuration to the VitNode app generator

Validation

• verified the updated Turbo configuration and package manifests parse as JSON
• ran pnpm --filter api lint: the updated ESLint command starts and loads the shared config; it then reports 5 existing type-aware errors in apps/api/src/index.ts
• ran pnpm format:check: the repository already has existing Prettier differences, so it is not yet suitable as a CI gate

The new root format / format:check commands are explicit; lint:fix remains lint-only and no longer triggers a repository-wide formatting rewrite.

Add formatting commands to standalone scaffolds

When singleApp or onlyApi is generated without --monorepo, createPackageJSON never uses rootScripts; it writes singleAppScripts or apiScripts, which only receive the new ESLint-only scripts. Because the shared ESLint configuration no longer invokes Prettier, these generated projects now have neither a formatting command nor a formatting check, and their former lint:fix workflow no longer formats files. Add the explicit Prettier scripts to the standalone script sets as well.

Ignore tool caches in generated projects

Mirror this ignore in the scaffold templates. The checked root, api, and monorepo .gitignore_template files contain no .cache pattern, while the newly generated lint and format scripts write under .cache/eslint and .cache/prettier (ESLint's --help defines --cache-location as the cache file or directory path). Consequently, running either command in a newly scaffolded project immediately leaves generated cache artifacts in git status.
