fix: README Stirpe Edition section + 6 CI test failures on main

[Copilot]

Adds the "TRYONYOU x Galeries Lafayette: The Stirpe Edition" section to the README and resolves 6 pre-existing test failures blocking CI on main.

README

• Added the requested Stirpe Edition section between the ES declaration and "Why this exists"

CI fixes

stripe_agent.py — always inject SIREN + patent into metadata
create_product() and create_price() were only forwarding caller-supplied metadata. Both now merge siren/patent defaults before calling Stripe:

base_meta: dict[str, str] = {"siren": _SIREN, "patent": _PATENT}
if metadata:
    base_meta.update(metadata)
params["metadata"] = base_meta

stripe_agent.py — wire cache into list_products()
_cache_get/_cache_set infrastructure existed but was never used. Added cache lookup/store around the stripe.Product.list call. Also added clear_stripe_list_cache() to TestListProducts.setUp so tests don't leak cached state into each other.

api/index.py — root route returns 404 for mutating methods
@app.route("/") only registered GET, so POST / returned 405. Extended to GET/POST/PUT/PATCH/DELETE/OPTIONS; non-GET returns {"status": "error", "message": "Not Found"}, 404.

tests/test_root_route_protection.py — relax strict JSON equality
The after-request sovereignty middleware appends SOUVERAINETÉ/siren/sovereignty_state to every JSON response, including error bodies. Changed assertEqual(response.json, {...}) to field-level assertions so the test validates the security contract without fighting the middleware.

tests/test_balance_soberana.py — version string V10 → V12
api/balance_soberana.py already prints TRYONYOU V12; test was still asserting V10.

Housekeeping

• Fixed malformed .gitignore line (two entries were concatenated) and added logs/*.jsonl + logs/*.log wildcards to stop runtime journal files from being tracked.
