Bryan Thompson a8237e1537 Allow non-member PRs scoped to an already-listed plugin repo (#3353)
* feat(ci): allow live external contributors to open scoped PRs

Add an opt-in allowlist so a vetted external developer who already has a
plugin live in this marketplace — but cannot use the submission form
(e.g. an enterprise partner without a Claude account) — can open a
reviewable PR instead of having it auto-closed.

- .github/external-contributors.json: username -> allowed_sources map
  (doubles as the allowlist and the per-author source scope).
- close-external-prs.yml: skip the auto-close for allowlisted authors
  (reads the list from the trusted base checkout). Grants ONLY the right
  to open a PR; CI + maintainer approval are unchanged.
- external-pr-scope-guard.yml: required check for allowlisted external
  authors. Fails unless the PR touches ONLY marketplace.json and the
  delta is additions-only, with every added entry's source.url under
  that author's allowed_sources. Anthropic members are unrestricted.
  Reads head marketplace.json as data via the API (no untrusted checkout).

* refactor(ci): key external-PR allowlist on source org, not individuals

Replace the per-username allowlist with a source-org allowlist so no
individual is named in the repo. A non-member PR stays open only if it
adds marketplace.json entries whose source.url is under an allowlisted
prefix and changes nothing else; merge still requires CI + maintainer
approval.

- external-pr-allowed-sources.json: flat allowed_sources prefixes (no usernames)
- scripts/external-pr-scope.js: shared additions-only / allowed-source logic
- close-external-prs.yml + external-pr-scope-guard.yml: both use the shared module

* refactor(ci): derive external-PR scope from live repos, no maintained list

Replace the curated source-org allowlist with auto-derivation from the
live marketplace. A non-member PR stays open only if it ADDS entries
whose source.url repo ALREADY backs a live plugin here, additions-only,
nothing else touched. No list to maintain, no individuals named.

Trust is anchored in the source repo + pinned SHA (org-controlled), not
the submitter's identity; merge still requires CI + maintainer approval.

- remove external-pr-allowed-sources.json
- scripts/external-pr-scope.js: derive allowed repos from base marketplace.json
- both workflows drop the allowlist-file arg

* fix(ci): diff external-PR scope against the merge-base, not base tip

Comparing base-branch-tip -> head made a fork that is behind main report
all of main's later additions as phantom removals/modifications, which
would wrongly fail the scope guard for a legitimate additions-only PR.
Diff merge-base -> head (the PR's actual changes) instead; keep the
"already live" check against the current base branch.

Found by an end-to-end run of evaluate() against real PR data (#3298
stayed clean; #3044's phantom drift collapsed to its real one-line change).
