docs(readme): complete health and quality badges

[rmems]

Motivation

• Complete the repository health and quality badge set by adding Codecov, Codacy, and Qlty maintainability indicators while retaining the existing CI, crates.io, docs.rs, and license badges.

Description

• Inserted three new badge links at the top of README.md: Codecov (https://codecov.io/gh/Limen-Neural/brainstem-daemon), Codacy (https://app.codacy.com/gh/Limen-Neural/brainstem-daemon/dashboard), and Qlty maintainability (https://qlty.sh/gh/Limen-Neural/projects/brainstem-daemon), with no other functional changes.

Testing

• Ran git diff --check and cargo fmt --check, and both commands completed successfully.

Codex Task

Summary by cubic

Adds Codecov coverage, Codacy code-quality, and Qlty maintainability badges to the README so the repository health badge set is complete. Existing CI, crates.io, docs.rs, and license badges remain unchanged. No Docker badge was added because there's no continuously verified image workflow.

^{Written for commit 4ccb502. Summary will update on new commits.}

CodeAnt Nitpicks

1 code suggestion

1. The repository CI does not generate or upload coverage, so this Codecov badge has no current coverage data and cannot report a meaningful status.

Add coverage uploads before displaying the Codecov badge

The checked .github/workflows/ci.yml only runs formatting, linting, builds, and tests, and a repo-wide search finds no coverage generation or Codecov upload step. Consequently this badge cannot be updated by pushes or pull requests and will display missing/unknown or stale coverage; add an instrumented coverage job and uploader before advertising Codecov, or omit the badge.

Useful? React with 👍 / 👎.

Use Codacy's generated project badge URL

For repositories connected to Codacy, the grade badge is served from Codacy's generated /project/badge/Grade/<project-id> endpoint rather than the dashboard-style /gh/<owner>/<repo>/badge.svg path used here. As written, the new image points at a non-badge route and renders as a broken badge; copy the project-specific badge URL from the Codacy dashboard.

Useful? React with 👍 / 👎.

[chatgpt-codex-connector]

Use Qlty's generated maintainability badge URL

Qlty serves maintainability badge images from its generated /badges/<badge-id>/maintainability.svg endpoint; the human-readable /gh/<owner>/projects/<project> path is the project page and does not become an image endpoint by appending /maintainability.svg. This URL therefore renders as a broken badge, so use the project-specific badge snippet generated by Qlty.
