Greptile SummaryThis PR adds a polished, color-gradient CLI help page using a custom Commander formatter and cleans up the README to use the Confidence Score: 4/5Safe to merge — all three issues are non-blocking cosmetic/DX nits with no impact on correctness or runtime behavior. The core change (beautiful help page + README cleanup) is well-implemented and correct. The three flagged items are all P2 style/best-practice issues: unused dead code, a minor --no-color inconsistency that only matters in a fairly rare edge case (TTY + explicit --no-color + --help), and the engines field removal which is a mild DX regression. None of these block functionality or cause runtime errors. cli/src/help.ts for the unused stripAnsi function and the --no-color / tty() inconsistency.

| Filename | Overview |
|---|---|
| cli/src/help.ts | New file: custom Commander help formatter with a seeded-PRNG gradient banner and Unicode box sections. Minor issues: unused stripAnsi function (dead code) and --no-color flag ignored during help rendering. |
| cli/src/index.ts | Integrates configureHelp, adds explicit -V, --version flags, and moves configureHelp call before command registration — correct ordering with Commander. |
| cli/package.json | Removes engines field (node: >=18.0.0), which means npm won't warn users on unsupported Node versions at install time. |
| cli/README.md | All node cli/dist/index.js invocations replaced with the grid global command; npm link step added to setup. Clean documentation improvement. |

**Unused `stripAnsi` function (dead code)**
`stripAnsi` is defined but never called anywhere in this file, and it's not exported. If TypeScript is configured with `noUnusedLocals: true` this will produce a compile error. Consider removing it or using it for alignment calculations if that was the original intent (e.g., stripping ANSI codes before calling `.padEnd` — though the current code already pads before adding color codes, so it's not needed).

Comment:
**`--no-color` flag not respected in help output**
The help formatter uses `process.stdout.isTTY` to decide whether to render ANSI colors. However, the `--no-color` CLI option (which calls `setUseColors(false)` via the `preAction` hook) is never consulted here, since Commander short-circuits command execution to show help before the hook fires.
This means running `grid --no-color --help` in an interactive terminal will still produce colorized output, which users might not expect. Consider accepting a `useColors` parameter or checking a module-level flag that respects `--no-color`:
```typescript
// In help.ts, expose a setter:
let _useColors: boolean | undefined;
export function setHelpColors(v: boolean): void { _useColors = v; }
function tty(): boolean {
return _useColors ?? (process.stdout.isTTY ?? false);
}
```
And call `setHelpColors(false)` when `--no-color` is parsed (e.g., in the `preAction` hook or immediately after option parsing).

stripAnsi function (dead code)
stripAnsi is defined but never called anywhere in this file, and it's not exported. If TypeScript is configured with noUnusedLocals: true this will produce a compile error. Consider removing it or using it for alignment calculations if that was the original intent (e.g., stripping ANSI codes before calling .padEnd — though the current code already pads before adding color codes, so it's not needed).
