Fork CI now requires a disposable channel allocation (R2_DISPOSABLE_RUN
guard in desktop-bundled-release.yml), but 'release.py --build-commit REV
--publish' still fired the old direct dispatch, so every fork commit build
died at admission. cmd_build_commit now detects a non-upstream repository
(case-insensitive NousResearch/hermes-agent compare), dispatches the
allocation workflow with disposable_channel/build_commit/bundle_env baked
in (all --bundle-env/--bundle-unset values travel inside the immutable
request; the follow-up never re-passes them), polls the allocation run to
completion (15s interval, 15min budget), extracts the printed follow-up
dispatch from the run logs (channel_disposable's single-line JSON
'command'), validates its shape (gh workflow run of this workflow against
the same repository), and auto-dispatches it with the local maintainer's
gh login — falling back to a clear run-summary pointer when log recovery
fails. Upstream behavior is unchanged. Also fixes a pre-existing TypeError
that masked check_output failures whose CalledProcessError has stderr=None.
