revert(create-melonjs): drop --template flag

[obiot]

Summary

Walks back the --template <name> / -t flag added to create-melonjs in #1439. Aligns with how the other plugins (@melonjs/spine-plugin, @melonjs/tiled-inflate-plugin, @melonjs/debug-plugin) work today — users scaffold the default boilerplate and npm install the plugin themselves.

The Capacitor wiki page (draft at /tmp/Capacitor.md) documents the manual steps. No new boilerplate repo or subfolder needed.

Why revert

Two undesirable downstream costs of the flag:

1. Maintaining a Capacitor-flavored boilerplate — either a separate typescript-boilerplate-capacitor repo (drift on every melonJS / @melonjs/* bump) or a capacitor/ subfolder of the existing repo (cleaner but still extra surface).
2. Or patching the default scaffold mid-install — the alternative without a separate boilerplate, but couples create-melonjs to the boilerplate's source layout (regex/AST edits to src/main.ts, package.json merges, etc.).

Neither is worth it. The Capacitor plugin is just npm install + a single plugin.register(...) call, same as the existing plugins.

Files

• packages/create-melonjs/bin/create-melonjs.js — back to 99 lines, no flag parsing.
• packages/create-melonjs/package.json — version stays at 1.0.1 (the 1.1.0 bump was never published).
• packages/create-melonjs/CHANGELOG.md — 1.1.0 entry removed.
• packages/create-melonjs/README.md — templates table removed.

The @melonjs/capacitor-plugin package itself is unaffected; this is create-melonjs-only.

Test plan

• pnpm lint — 0 errors.
• node bin/create-melonjs.js — usage banner is back to the original (no --template mention).

Pull request overview

This PR reverts the recently added --template/-t support in create-melonjs, returning the scaffolder to always using the default melonjs/typescript-boilerplate flow (with optional plugins installed manually afterward). This aligns create-melonjs with the existing plugin ecosystem approach.

Changes:

• Removed the templates section from create-melonjs README.
• Removed the 1.1.0 changelog entry describing template support.
• Simplified bin/create-melonjs.js to stop parsing --template/-t and always scaffold from the default boilerplate; package version set back to 1.0.1.
