Claude fbcd5422ee Build PR OTA bundle in parallel with the fingerprint check
publish-pr-ota needed fingerprint-native, so the bundle build - the slow
half - did not start until the fingerprint had finished, even though the
bundle does not depend on the fingerprint verdict. Only the decision to
publish it does.

Split the job in two: build-pr-ota builds and assembles the bundle with no
dependency on the fingerprint (so it runs alongside it) and hands it over
as a short-lived artifact, and publish-pr-ota keeps the fingerprint gate
and does just the denis publish. A dirty fingerprint now discards an
already-built bundle instead of saving the build, which costs a runner but
takes the fingerprint's wall clock off the critical path of every
fingerprint-clean PR.

Since the build job already has the EAS CLI set up, it also reads the
native build numbers and exposes them (along with the release version) as
job outputs, so the publish job needs neither EXPO_TOKEN nor node_modules
and can invoke denisPublish.sh directly rather than through the
use-build-number wrapper. denisPublish.sh gains SKIP_BUNDLE_ASSEMBLY for
that case, where bundleTempDir arrives as an artifact and ./dist is not
present; without it the script assembles the directory as before, so the
main-branch deploy is unaffected.

# Automatic per-PR OTA preview, published to the pull-request-<N> channel on
# denis. Replaces the old `@github-actions ota` comment trigger. Gated to
# same-repo PRs (fork guard): a branch can only exist in this repo if someone
# with write access pushed it, so an outside contributor (who can only open a
# PR from a fork) never runs this job with the denis publish role in scope.
# This matches the fork-guard gate the other jobs in this workflow use;
# author_association is deliberately NOT checked (it can't identify a private
# org member and would skip their PRs).
#
# Bot authors are excluded: Dependabot pushes in-repo branches, so it passes
# the fork guard, but GitHub withholds repo secrets from Dependabot-triggered
# runs. EXPO_TOKEN is then empty and the job fails at setup — a red check on
# every dependabot PR. There is no OTA preview worth publishing for a
# dependency bump anyway.
#
# The bundle is built here rather than in publish-pr-ota so it runs in
# PARALLEL with fingerprint-native instead of after it: both are multi-minute
# jobs, and the bundle does not depend on the fingerprint verdict - only the
# decision to publish it does. This job deliberately carries no AWS or denis
# credentials; it only produces an artifact. When the fingerprint turns out to
# be dirty the bundle is simply discarded unpublished, which costs a runner but
# saves the fingerprint's wall clock on every clean PR.
