Release v0.2.0

Added

• ci.yaml: new wasm-packages input (space-separated workspace members,
  default empty = whole workspace) narrowing which packages the per-target
  clippy passes lint. Workspaces that mix host-only crates with guest
  components can now pass targets: wasm32-wasip2 at all.
• mise/rust.toml: lint-host and lint-wasm (the two halves of lint),
  fmt-check, vet-regen and a cov coverage helper
  (cargo llvm-cov nextest --workspace --all-features --summary-only).
• mise/rust.toml: consumer knobs read from [env]: WASM32_PACKAGES
  (mirrors wasm-packages) and OUTDATED_IGNORE (comma-separated, mirrors
  audit.yaml's outdated input).
• README: consumer configuration, the wasm32 lint convention and a table
  mapping each ci.yaml job to its mise/rust.toml task.

Changed

• ci.yaml and mise/rust.toml (lint-wasm): the per-target clippy pass
  builds --lib --bins --examples instead of --all-targets, and the
  per-target cargo hack clippy --each-feature pass uses cargo's default
  targets (lib + bins). Integration tests and benches, whose dev-dependencies
  are host-only in most workspaces, are no longer compiled for wasm32.
  Convention: any bin or example in the wasm32 scope that is host-only must be
  cfg-gated to an empty main on wasm32.
• mise/rust.toml: vet is now check-only (cargo vet --locked), matching
  the CI vet job; the three regenerate steps moved to vet-regen.
• mise/rust.toml: ci runs exactly the CI jobs
  (fmt-check, lint, test, test-docs, docs, vet, deny).
  outdated and deps remain in check; fmt no longer rewrites sources
  as part of ci.
• mise/rust.toml: outdated no longer hard-codes omnia's ignore list; set
  OUTDATED_IGNORE instead.
• mise/rust.toml: lint passes --locked; RUSTFLAGS=-Dwarnings is set
  on lint, test, test-docs and docs, and docs also sets
  RUSTDOCFLAGS=-Dwarnings, so mise run ci matches the workflow's global
  environment.

What's Changed

• review reusability of mise and ci lint commands by @andrew-goldie in #42
