Wave 1, task T-4.3. Replaces the Phase 01 issue-to-contract.yml skeleton
with the real L3B trigger (D-030). On issue opened, the workflow checks out
the acdl repo at milestone/v1.0-initial (branch-pin rule) to obtain
l3b_agent_stub.py, parses the Issue body into contract.yaml, commits it to
a new branch contract/<issue-number> on acdl-contracts via the Gitea
file-contents API using the new_branch field (single POST creates the
branch + file), comments on and closes the Issue, then dispatches the
pipeline workflow on acdl via POST .../actions/workflows/pipeline.yml/
dispatches with inputs contract-ref=contract/<issue-number>
(cross-repo trigger per D-014). The `on:` key is quoted as "on": so
PyYAML parses it as a string key.

# ACDL issue-to-contract workflow (Phase 01 skeleton, reference copy).
#
# This file is the source-of-truth copy kept in the `acdl` repo under
# contracts-repo/.gitea/workflows/. Phase 04 will push it to the actual
# `acdl-contracts` repo under .gitea/workflows/ and implement the real
# step bodies.
# ACDL issue-to-contract workflow (Phase 04 implementation).
#
# Trigger: a new Issue is opened in acdl-contracts. The workflow runs
# l3b_agent_stub.py to map the Issue body to a contract.yaml, commits the
# contract to a new branch, closes the Issue, and triggers the main
# pipeline in the `acdl` repo via the workflow_dispatch API (D-014; Gitea
# Actions does not support repository_dispatch).
# l3b_agent_stub.py (checked out from the `acdl` repo, pinned to
# @milestone/v1.0-initial) to map the Issue body to a contract.yaml, commits
# the contract to a new branch `contract/<issue-number>` on acdl-contracts
# via the Gitea file-contents API, closes the Issue with a comment, and
# dispatches the main pipeline in the `acdl` repo via the workflow_dispatch
# API (D-014; Gitea Actions does not support repository_dispatch).
#
# Cross-repo trigger (D-014):
# The final step POSTs to
# /api/v1/repos/continuous-intelligence/acdl/actions/workflows/pipeline.yml/dispatches
# with body {"ref": "milestone/v1.0-initial",
# "inputs": {"contract-ref": "contract/<issue-number>"}}.
#
# Branch-pin rule (ARCHITECTURE.md):
# The `acdl` repo's default branch is `milestone/v1.0-initial`, so the
# checkout step pins `ref: milestone/v1.0-initial`. The pipeline dispatch
# also pins `ref: milestone/v1.0-initial` (the workflow file lives on
# that branch). The new `contract/<n>` branch is created on acdl-contracts
# (whose default branch is `main`, per D-015).
#
# File-contents POST with `new_branch` (D-030):
# The POST to /repos/.../contents/contract.yaml includes
# `new_branch: contract/<n>`, which tells Gitea to create the file on a
# NEW branch off the current head of `branch: main` instead of committing
# directly to main. This avoids a separate branch-create + commit round
# trip.
