## Summary
- Clarifies help text for `--reporter` and `--reporter-outfile` flags
- Improves error messages when invalid reporter formats are specified
- Makes distinction between test reporters and coverage reporters
clearer
## Changes
1. Updated help text in `Arguments.zig` to better explain:
- What formats are currently available (only 'junit' for --reporter)
- Default behavior (console output for tests)
- Requirements (--reporter-outfile needed with --reporter=junit)
2. Improved error messages to list available options when invalid
formats are used
3. Updated CLI completions to match the new help text
## Test plan
- [x] Built and tested with `bun bd`
- [x] Verified help text displays correctly: `./build/debug/bun-debug
test --help`
- [x] Tested error message for invalid reporter:
`./build/debug/bun-debug test --reporter=json`
- [x] Tested error message for missing outfile: `./build/debug/bun-debug
test --reporter=junit`
- [x] Tested error message for invalid coverage reporter:
`./build/debug/bun-debug test --coverage-reporter=invalid`
- [x] Verified junit reporter still works: `./build/debug/bun-debug test
--reporter=junit --reporter-outfile=/tmp/junit.xml`
- [x] Verified lcov coverage reporter still works:
`./build/debug/bun-debug test --coverage --coverage-reporter=lcov`

## Summary
This PR adds a comprehensive TypeScript CLI flag parser that reads the
`--help` menu for every Bun command and generates structured JSON data
for shell completion generators.
### Features
- **🔍 Complete command discovery**: Automatically discovers all 22 Bun
commands
- **📋 Comprehensive flag parsing**: Extracts 388+ flags with
descriptions, types, defaults, and choices
- **🌳 Nested subcommand support**: Handles complex cases like `bun pm
cache rm`, `bun pm pkg set`
- **🔗 Command aliases**: Supports `bun i` = `bun install`, `bun a` =
`bun add`, etc.
- **🎯 Dynamic completions**: Integrates with `bun getcompletes` for
scripts, packages, files, binaries
- **📂 File type awareness**: Knows when to complete `.js/.ts` files vs
test files vs packages
- **⚡ Special case handling**: Handles bare `bun` vs `bun run` and other
edge cases
### Generated Output
The script generates `completions/bun-cli.json` with:
- 21 commands with full metadata
- 47 global flags
- 16 pm subcommands (including nested ones)
- 54+ examples
- Dynamic completion hints
- Integration info for existing shell completions
### Usage
```bash
bun run scripts/generate-cli-completions.ts
```
Output saved to `completions/bun-cli.json` for use by future shell
completion generators.
### Perfect Shell Completions Ready
This JSON structure provides everything needed to generate perfect shell
completions for fish, bash, and zsh with full feature parity to the
existing hand-crafted completions. It captures all the complex cases
that make Bun's CLI completions work seamlessly.
The generated data structure includes:
- Context-aware flag suggestions
- Proper file type filtering
- Package name completions
- Script and binary discovery
- Subcommand nesting
- Alias handling
- Dynamic completion integration

Most CLI tools have the style convention of referring to themselves in
lowercase. It is, after all, the name that users type in when using
the tool. This PR maintains that convention in bun.
