Sieve playground: the server's interpreter in the browser
tools/sieve-playground builds the vendored sieve-rs 0.7.3 (vnd.inbuxa.*
names included) to WebAssembly, with a static page around it, for inbuxa
Admin's Debug button on a Sieve script: until now that button sent the
script to an outside site whose interpreter knows only upstream's
extension names, so any script that requires vnd.inbuxa.* failed to
compile there.

Ported from the playground in the upstream sieve-rs repository's web/
directory (commit 549a2d57f7), which targets sieve-rs 1.x:

- run.rs and handler.rs drive 0.7's event loop the way the server's
  delivery does, carrying on after a runtime error; llm_prompt compiles
  and answers false, as on a server without a model.
- The expression functions are the server's own modules, included by
  path; tests fail if the list, ApplyString or the few functions copied
  from misc.rs/unicode.rs stop matching crates/common.
- Built for wasm32-wasip1 rather than with wasm-bindgen: sieve-rs and
  mail-builder read the clock, which panics on wasm32-unknown-unknown.
  The page's worker answers the six WASI calls, giving the module the
  playground's current-time setting. shim/gethostname stands in for a
  crate with no WASI build. Nothing in vendor/ or crates/ changes.
- The page carries no upstream names or links; storage keys and the
  samples are renamed to match.

build.sh --admin <dir> stages the result into an inbuxa-admin checkout.
