Make the announcer source-control-neutral (#293)

The merged-PR announcer's enumeration already reads the
provider-neutral taskPullRequests table, which every source-control
provider's webhooks populate; only its eligibility gate forced a
GitHub installation. The gate now requires any active repository, the
manual-trigger requirement drops the github token for the neutral
repository check, and the registry declares support for all
source-control providers.

The security/code-quality auditors and conflict resolver stay
GitHub-only by declaration: the auditors read pullRequestFacts, which
only the GitHub sync writes, and conflict resolution needs a
list-open-PRs primitive no provider package has yet — both are real
per-provider workstreams, not gate changes.
