chore(eslint): re-enable @cdklabs rules after plugin fixes deprecated context.getFilename()

[scottschreckengaust]

Summary

Four @cdklabs/eslint-plugin rules are disabled in cdk/eslint.config.mjs because they use the deprecated context.getFilename() API which was removed in ESLint 10. Re-enable them when cdklabs publishes a fix.

Disabled rules

Rule	Purpose
@cdklabs/no-core-construct	Prevents use of deprecated core Construct class
@cdklabs/invalid-cfn-imports	Validates CloudFormation import patterns
@cdklabs/no-literal-partition	Catches hardcoded AWS partition strings
@cdklabs/no-invalid-path	Validates path references

Root cause

ESLint 10 removed context.getFilename() (deprecated since ESLint 9.x). The replacement is context.filename. The @cdklabs/eslint-plugin@2.0.6 (latest as of 2026-05-22) still calls the removed API, causing runtime errors during linting.

promiseall-no-unbounded-parallelism remains enabled as it doesn't use the deprecated API.

Action required

1. Monitor @cdklabs/eslint-plugin releases for a version that uses context.filename
2. When published: bump the dependency and remove the off overrides from cdk/eslint.config.mjs
3. Re-run mise //cdk:eslint — the 3 file-level @cdklabs/no-literal-partition suppressions in cdk/src/bootstrap/policies/ will become active again

Upstream

• Package: https://www.npmjs.com/package/@cdklabs/eslint-plugin
• Current: 2.0.6 (peerDeps: eslint >=9 <11 — claims ESLint 10 support but uses removed API)
• Consider filing an upstream issue at the cdklabs GitHub org if not already tracked
