## Description

The `cuckoo.MinimumLoad()` option was not a very useful option, and prone to error. By removing the ability to modify it, and setting it to something reasonable (like 5%), we can remove a whole set of errors that the user may stumble into.

## Changes

- Remove `MinimumLoad()` option.
- Privated `DefaultMinimumLoad`.

### Design Decisions

- `DefaultMinimumLoad` should be privated because it is no longer an option. The user should not need to interact with it.

## Checklist

- [x] Tests pass
- [x] Docs updated

ed30a4fc7c fix: check-pr-title job has prompt injection (#18)

## Description

Currently, the `check-pr-title` job has a security vulnerability. If you give the PR a bad title, the job can run arbitrary code.

## Changes

- Fix prompt injection by pulling the PR title as an environment variable.
- Also, restricted the job to only `pull_request` trigger.

### Design Decisions

- It is better to pull out this job into a separate workflow with a unique trigger, but I chose not to because it is currently only one job.

## Checklist

- [x] Docs updated

## Description

There were some problems with the roll-out of the issue templates. This PR addresses them.

## Changes

- Disable `blank-issue-enabled`.
- Move all `description` types in the issue templates to `placeholder`.

### Design Decisions

- The `description` fields take up too much space.

581f26f562 ci: support semantic versioning, conventional commits (#15)

## Description

Currently, the repository is not well suited for semantic versioning, and hasn't much to support it. This PR adds templates, CI jobs, and configs to simplify its adoption.

## Changes

- Added `FEATURE` and `BUG` issue templates. Also, forbids free-form issues.
- Adds a PR template.
- Adds a CI job to ensure the commit title follows conventional commits.

### Design Decisions

N/A.
