chore: update dependencies and improve code consistency

[Dmitrii Shilov (bk201-)]

This pull request makes extensive updates to the project's linting setup by removing ESLint in favor of a custom Oxlint plugin, updating dependencies, and refining VS Code configurations. The main goals are to streamline linting, enforce consistent code quality rules, and keep dependencies up to date. Additionally, it introduces minor improvements and bug fixes in language service error handling.

Linting and Tooling Overhaul

• Removed ESLint configuration and related dependencies, fully migrating linting to Oxlint with a new custom plugin (.oxlint-plugin.mjs). This plugin enforces license headers, import restrictions, and l10n usage conventions, and is integrated via .oxlintrc.jsonc. (eslint.config.mjs removed, .oxlintrc.jsonc, .oxlint-plugin.mjs, package.json, .vscode/settings.json, .vscode/tasks.json, .vscode/extensions.json) [1] [2] [3] [4] [5] [6] [7] [8]
• Updated VS Code settings to use Oxlint for code actions on save and removed the TypeScript SDK override, reflecting the shift away from ESLint. (.vscode/settings.json) [1] [2]
• Modified the lint task to remove ESLint-specific problem matchers. (.vscode/tasks.json)

Dependency and Engine Updates

• Upgraded Node.js and VS Code engine requirements to the latest versions, and updated a wide range of dependencies and devDependencies for compatibility and improved stability. (.nvmrc, package.json, packages/nosql-language-service/package.json) [1] [2] [3] [4] [5]

Custom Oxlint Plugin Implementation

• Added .oxlint-plugin.mjs with rules for:
  • Enforcing a standard Microsoft license header,
  • Restricting certain imports to encourage isomorphic code,
  • Enforcing direct usage of @vscode/l10n instead of vscode.l10n. (.oxlint-plugin.mjs)
• Updated .oxlintrc.jsonc to use the new plugin and rules, removing the old ESLint plugin and configuration. (.oxlintrc.jsonc) [1] [2]

Other Improvements and Fixes

• Added a new localization string for "Waiting for Azure Cosmos DB permissions to propagate…". (l10n/bundle.l10n.json)
• Improved error recovery in the SQL language service to handle cases where EOF token locations are unavailable. (packages/nosql-language-service/src/errors/SqlError.test.ts)

These changes modernize the development workflow, ensure code quality through more robust linting, and keep the project up to date with the latest dependencies and tooling.
