chore(repo): make clean scripts cross-platform (replace rm -rf with del-cli) (#8497)

Fixes #8496

- Updated all package.json clean scripts: rm -rf → del-cli
- Added del-cli as dev dependency at workspace root
- No runtime code changes, dev-only cross-platform fix
- Verified on Windows: clean/build/test now work vs previous rm errors

## Background

On Windows, `rm` is not available by default, causing all
clean/build/test commands to fail with `'rm' is not recognized as an
internal or external command`. This completely blocks Windows
contributors and CI runners from using the development toolchain.

The issue affects 40+ packages across the monorepo, all using `rm -rf`
in their clean scripts. @gr2m recommended the `del-cli` approach in the
issue comments.


## Summary

Replaced Unix-only `rm -rf` commands with cross-platform `del-cli` in
all package.json clean scripts:

- **Before**: `"clean": "rm -rf dist *.tsbuildinfo"`
- **After**: `"clean": "del-cli dist *.tsbuildinfo"`

Added `del-cli` as a dev-only dependency at the workspace root. No
runtime code changes, no published API changes.


## Manual Verification

**Before this PR (Windows PowerShell):**
```powershell
pnpm run clean
# Error: 'rm' is not recognized as an internal or external command
```

**After this PR (Windows PowerShell):**
```powershell
pnpm run clean    #  Works - cleans dist and .tsbuildinfo files
pnpm build        #  Works - builds successfully after clean
pnpm test         #  Works - 79/80 packages pass (RSC fails due to Playwright setup, unrelated)
```

**Cross-platform verification:**
- Unix/macOS behavior unchanged (del-cli works identically to rm -rf)
- All lint/type-check validations pass
