Establish INTENT.md/SCOPE.md and adopt TRSL V1C1 license

Maintainer decision, 2026-07-30: adopts TRSL V1C1 as this repo's
preliminary governing license, per target-revenue's
workplans/TREV-WP-0008-governance-and-pilot-rollout.md T05. Full
specialist legal review is deferred until out of beta (target-revenue
SCOPE.md section 1). No Phase is yet declared for this repo.

INTENT.md/SCOPE.md were missing; established from actual repo content
(README.md, SMOKE.md, commit history) rather than assumed product
scope: this repo is a disposable smoke-test target for rein-aharness,
not a product in its own right.

+# SCOPE
+
+## One-liner
+
+Disposable smoke-test target for `rein-aharness` (formerly `agent-harness`)
+— not a product, no independent feature scope.
+
+## In Scope
+
+- Being a safe, throwaway git target for `rein-aharness`'s automated
+  smoke-test runs (`SMOKE.md`, timestamped commits).
+
+## Out of Scope
+
+- Any real application code, product logic, or long-lived feature work.
+- Manual edits beyond occasional repo-hygiene (e.g. this file, `LICENSE`).
+- Anything that would make this repo's history load-bearing — it is
+  expected to be safely resettable/recreated if ever needed.
+
+## Relevant When
+
+You are working on `rein-aharness`'s smoke-test tooling itself, or
+auditing what its automated smoke runs actually do to a target repo.
+Not relevant for anything else.
