This major upgrade to ESLint v10 introduces significant breaking changes, most notably the complete removal of the legacy .eslintrc configuration system. All projects must migrate to the eslint.config.js (flat config) format.

Key Breaking Changes:

• Removal of .eslintrc: Support for .eslintrc.* and .eslintignore files has been completely removed. [1, 2, 7] You must migrate to a eslint.config.js file. [5, 10] Related CLI flags like --no-eslintrc and --ignore-path are also removed. [1]
• Node.js Version Requirement: Support for Node.js versions older than v20.19.0 has been dropped. [1, 2] You must ensure your environment is running a compatible Node.js version. [5]
• New Config Lookup: The configuration file is now located by searching from the directory of each linted file, which is a change from the previous behavior of searching from the current working directory. [1, 6]
• eslint-env Comments: Using /* eslint-env */ comments will now cause linting errors. [2, 5]

Recommendation:
This upgrade requires a mandatory migration of your ESLint configuration from the legacy .eslintrc format to the modern eslint.config.js flat config format. Follow the official Configuration Migration Guide before upgrading. [2, 10]

CRITICAL: ESLint 10 bump diverges from the catalog and is not synced to the lockfile, so it will fail install/lint.

This PR pins eslint to a hard-coded exact 10.0.0 while every other package still uses catalog:devTools (^9.39.2). Problems:

1. Lockfile not updated. Snyk's own PR description warns "Failed to update the pnpm-lock.yaml, please update manually before merging." The lockfile still resolves eslint@9.39.4 everywhere (grep of pnpm-lock.yaml shows no eslint@10). pnpm install in CI will be inconsistent / fail the lockfile check.
2. Inconsistent across the monorepo. All other packages (client, server, core, etc.) keep catalog:devTools. Bumping only hono means two ESLint majors coexist in one workspace, which pnpm/eslint peer resolution will reject.
3. ESLint 10 is a major breaking change (removes .eslintrc, requires flat config, Node >=20.19). The shared @modelcontextprotocol/eslint-config dep is still catalog:devTools (^9.39.2), so this package's eslint.config.mjs importing it would pull an incompatible peer. The whole monorepo must migrate to ESLint 10 together, not one leaf package.
4. Exact pin instead of ^10.0.0. Even if intentional, an exact 10.0.0 pin breaks the catalog-driven single-version-of-truth strategy this repo uses.

Recommendation: revert this line; fix the brace-expansion vuln at the catalog level (or bump all packages + shared config + lockfile together), since the fix belongs in catalogs.devTools.eslint in pnpm-workspace.yaml.

packages/middleware/hono/package.json	57	ESLint 10 bump diverges from catalog, is not synced to pnpm-lock.yaml (still eslint@9.39.4), and breaks monorepo-wide ESLint version consistency. ESLint 10 is a major breaking change requiring a coordinated migration (shared @modelcontextprotocol/eslint-config, all packages, and lockfile together). The brace-expansion vuln fix belongs in catalogs.devTools.eslint in pnpm-workspace.yaml, not an exact pin in one leaf package. Revert to "eslint": "catalog:devTools".
