[þing-01] Kill the implicit ensemble-dotenv borrow; entry validation per D6

[Polichinel]

Context: the platform's Appwrite-seam identity/config was folk knowledge — one unowned laptop .env as origin, one all-powerful key, and misconfiguration that silently succeeds into phantom storage. The ratified verdict fixes this via one contract ADR (PLATFORM-001), one owned coordinates registry file, declared classification, three credential tiers, and raise-by-default failure semantics.

Do (orð_09 §4 commitment — declared meanwhile, killed on this issue): delete load_dotenv(dotenv_path=str(self.ensemble_path_manager.dotenv)) (unfao.py:180) — the runtime edge of the copy-chain. The launcher (views-models M3) becomes explicitly responsible for the environment; this manager's entry validates the required names fail-loud (à la the registry preflight), naming every missing variable. Ordered: registry exists (A3) → M3 merged (launcher declares) → this lands. Cross-ref models #280 retargeting.

Done — PR #137 (merged into development). The borrow (load_dotenv at old unfao.py:180, þing-01 copy-chain edge S6ii) is dead: import + call deleted. New unfao/appwrite_env.py declares the required names (PLATFORM-001 registry connection+target classes + the one operator secret slot) and assert_env_declared() raises naming every missing variable — called before all three AppwriteConfig constructions. Prerequisite honored: views-models M3/#287 merged first (run.sh reads the registry; transitional .env fallback stays until #280 retires it). 7 guards incl. borrow-is-dead source scan, declaration↔use drift, and the D3 naming rule. This closes my orð_09 §4 commitment.
