🚀 Release 0.8.2

Add a short README section under Alternatives, one heading per
alternative (ts-pattern, Effect.Match, match-iz and plain switch), each
saying what it is and what tiny-pattern-ts is or does differently. State
the data-last, pipe-friendly shape in Description.

- measure the footprint: ~0.2 kB minified + gzipped, not the
  unminified ~1.8 kB; ts-pattern is ~2 kB
- correct match-iz: it ships types, it just cannot prove exhaustiveness
- drop switchcase / ts-match (unmaintained)
- check off the backlog task

Resolves: backlog "Add comparison section vs. other TS pattern-matching libs"

 The main goal of `tiny-pattern-ts` is to make pattern matching type-safe with a
 lean syntax. This is accomplished by being exhaustive and passing typed

+## Alternatives
+
+### [`ts-pattern`](https://github.com/gvergnaud/ts-pattern)
+
+- is the full structural matcher — nested and partial patterns, guards, unions,
+  captures — exhausting at `.exhaustive()`
+- has a fluent `.with(…)` chain that is heavy on syntax; tiny-pattern-ts is one
+  handler map
+- is about 2 kB minified and gzipped; tiny-pattern-ts is 0.2 kB
+- reach for it when you need a feature tiny-pattern-ts does not cover
+
+### [Effect's `Match`](https://effect.website/docs/code-style/pattern-matching/)
+
+- is the same piped matcher (`Match.type` / `Match.when` / `Match.exhaustive`),
+  but only as part of the `effect` ecosystem
+- tiny-pattern-ts is standalone: no runtime dependency to buy into
+
+### [`match-iz`](https://github.com/shuckster/match-iz)
+
+- expresses patterns in the TC39 proposal's style, deciding each case at runtime
+- is written in JavaScript with hand-maintained declarations, so its types do
+  not prove the cases exhaustive
+- tiny-pattern-ts does: exhaustiveness is a compile-time guarantee, not an
+  `otherwise` fallback
+
+### plain `switch` (baseline)
+
+- is the zero-dependency baseline — pair it with
+  [`eslint-plugin-strict-pattern-matching`](https://www.npmjs.com/package/eslint-plugin-strict-pattern-matching)
+  for exhaustiveness
+- is a statement, not an expression, so it cannot produce a value directly
+- leaves the `never` guard to you; tiny-pattern-ts is an expression and does not
+  need one
+
+The [TC39 pattern-matching proposal](https://github.com/tc39/proposal-pattern-matching)
+is still stage 1, so userland libraries remain the only option today.
