DLC: Code Quality Check

Run code quality analysis against the current project and create a GitHub issue with findings.

Before running, read ../dlc/references/ISSUE-TEMPLATE.md now for the issue format, and read ../dlc/references/REPORT-FORMAT.md now for the findings data structure.

Step 1: Detect Linting Config

Scan for linting configuration and project type:

Config File	Linter	Language
`.eslintrc` / `eslint.config.` / `biome.json`	ESLint / Biome	JS/TS
`ruff.toml` / `pyproject.toml` (with `[tool.ruff]`)	Ruff	Python
`.golangci.yml` / `.golangci.yaml`	golangci-lint	Go
`clippy.toml` / `Cargo.toml`	Clippy	Rust
`.rubocop.yml`	RuboCop	Ruby
