Weekly release

Weekly release #3

name: Weekly release
# Automated weekly version bump and release.
#
# Creates a PR to bump version.txt and fstar.opam to the current date,
# enables auto-merge, waits for CI to pass and the PR to merge, then
# dispatches the release workflow on the exact merge commit.
#
# Requirements:
# - "Allow auto-merge" must be enabled in repo settings
# - Branch protection must not require PR reviews (or the bot must
# be able to satisfy them)
