fix(runtime): unify the Intelligence key name and publish the wiring (refs OSS-881) (#6595)

## What does this PR do?

Closes the naming and documentation half of
[OSS-881](https://linear.app/copilotkit/issue/OSS-881). Paired with
CopilotKit/Intelligence#890, which adds `copilotkit verify` and tightens
the evaluation rubric.

### 1. One name for the Intelligence key

**Three** names for one value were live in CopilotKit's own
documentation, and following the wrong one with a CLI-provisioned
project yields an undefined key:

| Name | Where | Code readers |
| --- | --- | --- |
| `INTELLIGENCE_API_KEY` | what `copilotkit project select` writes; all
34 integration examples; the docs site | 34 |
| `COPILOTKIT_INTELLIGENCE_API_KEY` | 7 Channels package READMEs +
packaged skills | **0** |
| `COPILOTKIT_API_KEY` | `examples/slack`, `examples/teams`, and the
TSDoc on `CopilotKitIntelligence` itself | 2 |

`INTELLIGENCE_API_KEY` wins — it is the name the CLI provisions, and
changing it would break every scaffolded project in the wild.

- `COPILOTKIT_INTELLIGENCE_API_KEY` is **retired outright**. Nothing
ever read it, so there is nothing to keep compatible.
- `COPILOTKIT_API_KEY` stays **readable as a deprecated alias** in the
two examples that consume it, so an existing `.env` keeps working, and
is documented as deprecated everywhere it appears.

The third name was the worst placed: it was in the TSDoc on
`CopilotKitIntelligence`, which is what an IDE shows on hover.

This was not only untidy. The CLI's own `channels-preflight` accepts
`INTELLIGENCE_API_KEY` or `COPILOTKIT_API_KEY` — **not**
`COPILOTKIT_INTELLIGENCE_API_KEY`, the name the Channels READMEs told
people to set. So following a Channels README verbatim made `copilotkit
channels` warn that no runtime API key was present while the key sat
visibly in `.env`. After this PR the documented name is one preflight
accepts.

> [!NOTE]
> `NEXT_PUBLIC_COPILOTKIT_API_KEY` is a **different value** — the legacy
Copilot Cloud public key — and is deliberately left alone.

### 2. A real defect, not just naming skew

`skills/runtime/references/intelligence-mode.md` documented
`organizationId` as a `CopilotKitIntelligence` option, sourced from two
further env names (`COPILOTKIT_INTELLIGENCE_ORG_ID`,
`COPILOTKIT_ORG_ID`).

`CopilotKitIntelligenceConfig` has no such field — the copy-pasteable
sample it appeared in **would not compile**. Removed from the samples,
and the prose telling readers to fetch a value for it corrected. That
file is the only place those two names ever existed, which is very
likely why the failing validation run reported that "the runtime reads
`COPILOTKIT_INTELLIGENCE_API_KEY` and `COPILOTKIT_INTELLIGENCE_ORG_ID`".

### 3. Publish the Intelligence wiring

The wiring instructions existed only inside
`node_modules/@copilotkit/runtime/skills/`, and the only docs pages
mentioning `CopilotKitIntelligence` at all were the two Channels
frontends — so a developer on the plain web path had no page to reach it
from.

Adds **`/premium/connect-your-runtime`**: the wiring itself, how to
confirm the credential is actually consumed, the self-hosted
both-URLs-or-neither rule, and a troubleshooting table. Linked into both
navs, and the skills reference now points at the published page.

### 4. A guard so it cannot drift back

`scripts/validate-intelligence-env-names.ts` (`pnpm
check:intelligence-env-names`), wired to lefthook and a new workflow.

The workflow is **intentionally unfiltered**. The two workflows that
would otherwise cover this both filter: `plugin-skills-check` by
`paths:`, and `static/quality` by `paths-ignore: examples/**` — which is
exactly where the deprecated alias lives. Scoping the job would re-open
the hole it exists to close. Legitimate alias sites live in
`ALIAS_ALLOWLIST`.

## Related PRs and Issues

- [OSS-881](https://linear.app/copilotkit/issue/OSS-881) — needs
**both** PRs; neither closes it alone
- CopilotKit/Intelligence#890 — items 1 and 4 (`copilotkit verify` +
rubric contract 1.3.0)

## Verification

- Full lefthook pre-commit ran green: `check-plugin-skills`, `lint-fix`,
the new `check-intelligence-env-names`, and `test`/`publint`/`attw`
across **25 projects**.
- `examples/slack` `managed.test.ts` extended to cover **both** the
canonical name and the alias fallback, and proven non-vacuous — removing
the fallback turns the new test red.
- The drift guard proven non-vacuous the same way: reintroducing a
retired name fails it, exit 1.
- `oxfmt` and `oxlint` clean on every file touched (0 errors).
