fix(vscode): make the packaged .vsix actually load (Refs #62) (#63)

Building the .vsix per #62 surfaced a wiring defect: PR #58 switched the
compile to `--vscode-extension` codegen, whose auto-glue emits a top-level
`require("@hyperpolymath/affine-vscode")` — an unpublished npm package — while
the repo still routed activation through the hand-written `src/index.cjs` +
vendored `src/affine-vscode-adapter.cjs`. Result: VS Code loaded
`src/index.cjs` -> `require("../out/extension.cjs")` -> MODULE_NOT_FOUND on
`@hyperpolymath/affine-vscode`; the extension crashed on activation.

Fix, using the mechanism affinescript already provides:

- `compile`/`vscode:prepublish`: pass
  `--vscode-extension-adapter=../src/affine-vscode-adapter.cjs` so the
  auto-glue requires the already-vendored adapter by relative path (no npm
  package, resolves offline). `affinescript compile --help` documents this
  flag precisely for "vendoring a custom adapter".
- `main`: `./src/index.cjs` -> `./out/extension.cjs` — the directly-loadable
  entry the `--vscode-extension` codegen is designed to produce (#58/#105's
  stated end-state). `src/index.cjs` is now dead and removed.
- `vscode:prepublish`: no longer shells through `npm run` (repo CLAUDE.md
  bans npm) — it is the affinescript invocation directly.
- Add `.vscodeignore` so lockfiles/build noise stay out of the .vsix.
- `.gitignore`: ignore bun/deno lockfiles and the built `*.vsix`
  (distributed via GitHub Release, not git), extending the #57 policy.

Verified: `out/extension.cjs` loads standalone; from the packaged .vsix's
bundled tree `extraImports()` returns {Vscode, VscodeLanguageClient} with
only host-provided `vscode` stubbed; `activate`/`deactivate` present.
`my-lang-0.3.0.vsix` (324 files) now packages as a *functional* artifact.
