* ✨ add snapshot() for pre-packing directive subtrees

Introduces a new `snapshot(ops)` constructor that pre-packs a directive
array into its transfer encoding. The returned opaque `Op` can be
spliced into any directive array, and during packing its bytes are
copied directly into the command buffer without re-encoding.

This enables higher-level frameworks to implement dirty tracking:
unchanged component subtrees can reuse a cached snapshot, skipping
the per-frame packing cost entirely.

* docs: add maintainer build guide

* 💄 format build docs

* 🐛 improve pack string overflow errors

* os matrix test in ci (#36)

* 🧼 optimize build

* 🧼 compress bundled wasm

* 🧼 optimize wcwidth.c size

* ⚙️ update npm settings

* 🐛 install wasm-opt in ci

* ⚡ use brotli-11 + z85 wasm encoding

* 📌 pin @types/node to v22

* 🧼 apply @ghostdevv review suggestions from PR #35

* 🔨 add type to bundle-wasm

* 💌 signed, sealed, delivered

* chore: use hashes for versions

* chore: don't save git credentials

* chore: use array syntax

for some reason the schema for the actions wants it to be an array

* perf: set concurrency limits to reduce cost and improve dx

Without this it means that, for example, if I push a change to a PR then
shortly push again this workflow will be running twice. This change will
cancel the old run before starting the new one, which reduces the
overall actions cost and DX as you don't have extra runs

* 🙅 revert aggressive optimization experiments pending benchmark

Reverts three changes that need benchmarks before landing:
- -Oz / wasm-opt
- brotli+Z85 wasm compression
- wcwidth.c rewrite

* Add CodSpeed performance benchmarks

* 🔨 use deno

* 🧼 deno fmt

* ⚙️ vitest -> tinybench

* 🧼 remove codspeed assets

* 🔨 fix ci

* add type module

* fmt

* chore: update github url (#38)

* downgrade to tinybench@5

* move to examples folder with readme

* 🔧 export animating from wasm build

* 🧪 cover transitions in snapshots and validation

* ✅ enforce nonnegative transition duration
