internal/wasmtools, Makefile: add gzip compression for wasm-tools.wasm and update Makefile

This adds gzip compression for the wasm-tools.wasm to further reduce the size to 1.2M from 3.5M.
Added the wasm file to the .gitignore and thus the remote repo will only have the gzip file.
Updated Makefile to zip and unzip the Wasm module.

.github/workflows: remove some (now) unneeded steps

.gitignore: condense internal/wasmtools/.gitignore

internal/wasmtools: use single quotes, add Rust edition

Makefile: update order of wasm-tools.wasm.\* targets)

internal/wasmtools: use gzipped wasm-tools.wasm.gz with sync.Once

internal/wasmtools: rebuild wasm-tools.wasm.gz

CHANGELOG: wordsmith the wasm-tools and Wazero update

internal/wasmtools, wit: remove optional name arg

Removing this did not seem to affect tests.

internal/wasmtools: leave timeout to the caller

Makefile: reorder gzip targets

internal/wasmtools: oops

Makefile: next try

wit: remove check for wasm-tools in PATH

internal/wasmtools, wit: swap key and value types for fsMap

Not all fs.FS are hashable, but all strings are, so use map[string]fs.FS instead.

wit/bindgen: use internal/wasmtools to run wasm-tools in WebAssembly

internal/wasmtools: use wazero.CompilationCache

This speeds up wit/bindgen tests 10x

internal/wasmtools: fix TinyGo impl

internal/wasmtools: remove Runner interface

This wasn’t used anywhere, so removing.

internal/wasmtools: change Run() to accept optional stdout and stderr

internal/wasmtools: move args to varadic trailing arg in Run

wit: (*testing.common).Errorf does not support error-wrapping directive %w

internal/wasmtools, wit/bindgen: additional cleanups for TinyGo and WASI

.github/workflows/test: TinyGo needs wasm-tools for -target=wasip2

.github/dependabot: add internal/wasmtools for Cargo updates

cmd/wit-bindgen-go, internal/{module,witcli}: extract module helper into new package

internal/wasmtools: try to use disk-based compilation cache in TMPDIR

internal/cmd/wasm-tools: add Wazero-based wasm-tools executable

This removes the requirement for wasmtime in the Makefile

Makefile: use Wazero-based internal/cmd/wasm-tools executable instead of Wasmtime

.github/workflows/test: ignore all Markdown files

internal/wasmtools: rebuild wasm-tools.wasm.gz

internal/{cmd/wasm-tools,wasmtools}, wit: default mapping of ./ and / directories

.github/workflows: install wasm wrapped in Go version of wasm-tools

all: revert 26c1e72; Wazero directory handling tricky to manage

Wazero flattens ./ into '', which is treated as /, overriding the / mapping.

Makefile: just use wasm-tools

It’s faster, and works with arbitrary paths.
