/* Generated with following prompt:
You are generating a dictionary of command-prefix arities for bash-style commands.
This dictionary is used to identify the "human-understandable command" from an input shell command.### **RULES (follow strictly)**1. Each entry maps a **command prefix string → number**, representing how many **tokens** define the command.
2. **Flags NEVER count as tokens**. Only subcommands count.
3. **Longest matching prefix wins**.
4. **Only include a longer prefix if its arity is different from what the shorter prefix already implies**.   * Example: If `git` is 2, then do **not** include `git checkout`, `git commit`, etc. unless they require *different* arity.
5. The output must be a **single JSON object**. Each entry should have a comment with an example real world matching command. DO NOT MAKE ANY OTHER COMMENTS. Should be alphabetical
6. Include the **most commonly used commands** across many stacks and languages. More is better.### **Semantics examples*** `touch foo.txt` → `touch` (arity 1, explicitly listed)
* `git checkout main` → `git checkout` (because `git` has arity 2)
* `npm install` → `npm install` (because `npm` has arity 2)
* `npm run dev` → `npm run dev` (because `npm run` has arity 3)
* `python script.py` → `python script.py` (default: whole input, not in dictionary)### **Now generate the dictionary.**
