## Problem

The `--include` flag help text says "Comma-separated content to include: thinking, output." but clap does not enumerate the valid tokens in `--help` output. Users cannot discover valid values from `--help` alone.

## Current declaration (`src/cli.rs`)

```rust
/// Comma-separated content to include: thinking, output.
#[arg(long, global = true, default_value = "")]
pub include: IncludeList,
```

The valid tokens are `thinking` and `output` (parsed in `IncludeList::from_str`).

## Expected behavior

The help output should clearly show: `[possible values: thinking, output]` or equivalent. Options:

1. Update the `#[arg(help = ...)]` string to explicitly state the valid values and format.
2. Or use clap's `value_parser` with a custom validator that also shows valid choices.

Since `IncludeList` is a comma-separated composite (not a single enum value), option 1 (explicit help string) is simplest.

## Relevant files

- `src/cli.rs` — `IncludeList`, `GlobalOpts`, the `include` field annotation

## Summary of Changes

Updated the doc comment on the --include field in src/cli.rs to explicitly enumerate valid values (thinking, output) and provide an example.
