Stdlib-only asyncio package driving a child 'h5i orchestra serve' over
line-delimited JSON-RPC. Conductor/Agent mirror the Rust eDSL 1:1 (hire,
work/ask/review/revise, freeze, verify, judge, apply, step/scope/patched,
gate, preflight, trace); custom verdict policies are plain Python callables
committed through judge_begin/commit; on_turn= lets a score (or a test)
play the launcher. Typed frozen dataclasses carry the server's raw payloads
back verbatim for forward compatibility; errors map to a typed exception
hierarchy raised in the score's own stack frame. The patterns layer
(ensemble/integrate/pipeline/arena/map_reduce/judge_panel/debate) is ported
to public Python, port-faithful including the approval heuristic, the
independence expectations and the mean-score tie-break. Tests: 30 unit tests
against an in-process protocol mock + 2 integration tests against the real
binary, including a cross-process ensemble with scripted sh boxes mirroring
tests/orchestra_subprocess.rs.

… scores

Per-pattern: arena (ranked independent attempts + compare rows + gated
apply), pipeline (architect->implementer->hardener over materials),
judge_panel (rubric scoring over recorded evidence, judges hired pre-seal),
debate_then_build (conclusion steers work turns in the same run). Composed:
review_escalation (cheap-model-first ladder, senior takeover with the junior
artifact as material) and tournament (bracket of arena matches as separate
runs, semifinals concurrent — multi-run orchestration as plain function
calls). examples/README.md indexes them by when-to-reach-for-it; all
compile- and import-checked.

…ry integration)

test.yaml: ruff; pytest on 3.10-3.13 (integration auto-skips without a
binary); sdist/wheel build + twine check + clean-venv import; and an
integration job that checks out h5i-dev/h5i (branch-matched to the PR's
branch, falling back to main), builds the engine with rust-cache and
H5I_SKIP_WEB_BUILD=1, and runs the cross-process suite against the real
'h5i orchestra serve' — with a visible warning instead of a silent skip
while the bridge isn't on the engine's default branch yet.

release.yaml: on v* tags — verify tag==pyproject version, build, twine
check, publish via PyPI Trusted Publishing (OIDC, 'pypi' environment), and
attach dists to a GitHub release.

Also fixes the two ruff findings (unused asyncio import, E731 lambda) and
adds ruff to the dev extras.

… fix

The engine's H5I_SKIP_WEB_BUILD flag didn't create the web/dist folder
rust-embed requires at compile time (fixed upstream in h5i d18c953e, which
stubs it from build.rs); the mkdir keeps older engine refs — notably the
main-branch fallback — building too.
