metatroncubeswdev 381c52d01a fix: replace hand-scaffolded Functions with real CLI-generated ones
The user linked the app to a real Partner org and hit two live errors
running `shopify app dev`, which is exactly the verification the earlier
hand-scaffolded Functions couldn't get in this environment. Root-caused and
fixed both, then went further: regenerated both Functions from scratch via
`shopify app generate extension` (now possible — the user's session had
authenticated) instead of patching the guesses.

What broke and why:
- `shopify app config link` pulled a fresh app's (empty) remote config and
  overwrote shopify.app.toml, dropping the webhook subscriptions and
  app_proxy block — restored both, keeping the real client_id/name/scopes
  the CLI set.
- `[extensions.build.watch]` as a nested table was invalid TOML for this
  field — it's a plain `watch = [...]` array directly under
  `[extensions.build]`.
- The real failure ("doesn't have a build command or it's empty") turned
  out to be a red herring pointing at a stale filename
  (shopify.function.extension.toml, not the current shopify.extension.toml)
  — the actual problem was that `@shopify/shopify_function` was never
  installed for these extensions (confirmed: no node_modules), because
  hand-writing package.json doesn't run the install step
  `shopify app generate extension` does automatically.

Rather than keep guessing at the toolchain, regenerated both Functions for
real:
- `shopify app generate extension --template=cart_checkout_validation` and
  `--template=delivery_customization` (--flavor=vanilla-js), which produces
  a working vite/vitest-based build+test setup, real
  `@shopify/shopify-function-test-helpers` fixture testing (builds actual
  WASM and runs it via function-runner), and a generated GraphQL type file
  per extension.
- This surfaced several concrete corrections to what was hand-written
  before: the real target names are `cart.validations.generate.run` and
  `cart.delivery-options.transform.run` (not `purchase.validation.run` /
  `purchase.delivery-customization.run`), current api_version is 2026-07
  (not 2025-01), the validation output wraps errors in
  `operations: [{ validationAdd: { errors } }]` with a plain `message`
  field (not top-level `errors` with `localizedMessage`), and the rename
  operation is `deliveryOptionRename: { deliveryOptionHandle, title }` (not
  `rename: { deliveryOptionHandle, title }`).
- Rewrote each extension's `.graphql` input query to request our actual
  dd_* cart attributes (plus delivery option handles for the rename case),
  regenerated types via `npm run typegen` in each, and ported the pure
  evaluate.js decision logic (same exported function names/behavior as
  before, now proven correct against the live schema) into the adapter
  file the generator expects.
- Replaced each extension's demo fixture with ones matching our real
  logic; `npm test` inside each extension now compiles real WASM and runs
  function-runner against them — this is strictly stronger verification
  than the previous pure-JS-only unit tests (which are kept too, unchanged,
  since the evaluate.js files kept the same interface).

Repo-wide wiring: extensions/*/generated and extensions/*/dist are not
committed (matches the CLI's own per-extension .gitignore) — added
`npm run typegen:functions` (runs automatically before `npm run typecheck`
via a pretypecheck hook) and `npm run test:functions`, both now also in CI.
Root `npm install` picked these two folders up as proper npm workspace
members (they already have their own package.json from generation).

Verified: lint, typecheck, all 52 unit tests, all 8 integration tests, both
extensions' real WASM/function-runner test suites (5 fixtures total), and
both `npm run build` / `npm run build:widget` all pass.
