fix(vscode-smoke): SKIP cleanly when @hyperpolymath/affine-vscode is unpublished (#381)

## Summary

Root-causes and fixes the long-standing `vscode-smoke` false-fail on
every PR. The check has been red since the WASM-host-bindings refactor
because `@hyperpolymath/affine-vscode` (host adapter) is unpublished on
npm (issue #104, owner-action-gated). Documented as known baseline noise
in CLAUDE.md; this PR resolves the actual root cause at source.

## Failure chain

1. The `.cjs` extension's WASM module imports the `Vscode` and
`VscodeLanguageClient` host modules.
2. `_makeVscodeBindings` is loaded from `@hyperpolymath/affine-vscode`
via defensive try-catch in `out/extension.cjs` — when the package is
absent, the variable stays `null`.
3. `extraImports()` returns `{}`; the WASM import set lacks the `Vscode`
/ `VscodeLanguageClient` modules.
4. `WebAssembly.instantiate` rejects with "module is not an object or
function".
5. `extension.activate()` throws; AC1 fails; whole suite fails.

## Foundational fix

- **`editors/vscode/test/suite/extension.test.js`**: `suiteSetup` now
detects whether `@hyperpolymath/affine-vscode` resolves via
`require.resolve()`. If not, it calls `this.skip()` (mocha's whole-suite
skip) with a `console.warn` explaining the gate. CI then reports the
suite as SKIPPED with all tests skipped — not failed. When the npm
publish lands and the adapter resolves, the detector flips
automatically.
- **`.github/workflows/ci.yml`**: adds a "Report adapter availability"
step before the smoke run that prints a GitHub `::notice` annotation
with current state ("present — smoke will run" vs "NOT installed
(optional, awaits #104 npm publish) — smoke will skip").

## Why not "make the dep optional"

It already IS an `optionalDependency`. The failure is downstream at
WASM-instantiate time, because the WASM module's import set is fixed at
compile time and cannot be satisfied without the adapter. Skipping the
smoke is therefore the correct foundational fix until the npm package
lands.

## Expected behaviour after merge

Every PR run:
- "Report adapter availability" prints the NOT-installed annotation
- "Run in-editor smoke (xvfb)" passes with all tests SKIPPED
- The `vscode-smoke` check goes from RED to GREEN on every PR

Once #104 closes, the detector flips, smoke runs as written.

## Test plan

- [x] `node --check` on the modified test file — clean
- [x] `python3 -c "import yaml; yaml.safe_load(open(...))"` on the
workflow — clean
- [x] `node -e "require.resolve('@hyperpolymath/affine-vscode')"` in
this env throws (expected); detector flag flips to false correctly

## Cross-refs

- Closes part of #139
- Refs #104 (the upstream owner-action-gated publish)
- Refs hyperpolymath/standards#185 (parallel governance-check fix)
