* fix(plugins): add missing secret-input-schema build entry and Matrix runtime export
buildSecretInputSchema was not included in plugin-sdk-entrypoints.json,
so it was never emitted to dist/plugin-sdk/secret-input-schema.js. This
caused a ReferenceError during onboard when configuring channels that use
secret input schemas (matrix, feishu, mattermost, bluebubbles, nextcloud-talk, zalo).
Additionally, the Matrix extension's hand-written runtime-api barrel was
missing the re-export, unlike other extensions that use `export *` from
their plugin-sdk subpath.
