fix(formula): retire the `js` expression dialect and fix the `hasDialect` false-positive (#3278)
7+
8+
The `js` **expression** dialect was declared in `ExpressionDialect` but never
9+
shipped — it existed only as a registry stub with no engine and no author helper
10+
(`cel`/`F`/`P` → CEL, `tmpl` → template, `cron` → cron; nothing ever emitted
11+
`js`). Per ADR-0049 (enforce-or-remove) it is removed from the enum; the set is
12+
now `{cel, cron, template}`.
13+
14+
Procedural JavaScript is unaffected: it remains the **L2** authoring surface —
15+
the sandboxed, capability-gated `ScriptBody { language: 'js' }` in hook/action
16+
bodies — which is a separate enum (`hook-body.zod.ts`), not an expression
17+
dialect.
18+
19+
Also fixes a latent bug in `hasDialect`: it detected stubs via
20+
`dialect.startsWith('stub:')`, but stubs were registered under their real name,
21+
so the check was dead code and `hasDialect('js')` returned a false-positive
22+
`true`. With the stub removed, `hasDialect` reports only registered real
23+
engines, and the registry test now asserts the negative case (`hasDialect('js')
24+
=== false`) so the gate can actually go red.
25+
26+
No runtime behavior changes for any valid persisted artifact — no producer ever
27+
emitted `dialect: 'js'`. See the ADR-0058 addendum.
