tmu a3eb6183af 🔥 Remove the match and pattern example modules
They were the template's demo API, not the library's real surface. Drop
them, their README walkthrough, and the tooling note that cited their
disable directives, and point index.ts at the primitive matchers that
remain.

# tiny-pattern-ts
Pattern matching for TypeScript/ESM environments (F#-style, not regex).
## Description
`tiny-pattern-ts` brings F#-style pattern matching to TypeScript. Patterns are
ordinary objects whose `matches` method is a TypeScript type guard, so narrowing
composes the way any other guard does. It is deliberately not a regex engine and
not a macro: there is no transpiler and no DSL to learn, and the type-level
contract is the feature — see [development/library.md](./development/library.md)
for the design decisions and the known limitations.
## Requirements
- **Node.js >= 26** (`engines` field; pinned via `.node-version`).
- **TypeScript >= 5.0** to consume the published declarations. The emitted `.d.ts`
use `const` type parameters (TS 5.0) and keep their relative `.ts` specifiers;
both resolve on TS >= 5.0 in `node10` / `node16` / `nodenext` / `bundler`.
- The package is **ESM-only** (no CommonJS shim).
