LICENSE: tighten Keysat Source-Available License to v1.0

Custom source-available license, sharpened against several
ambiguities flagged in license review. Substance unchanged from
intent: operators can audit, run, modify, and sell licenses for
their own products through an instance they operate; reselling
the software itself or running it as a managed service for third
parties is forbidden. SDKs remain MIT in their own repos.

Concrete edits versus the prior draft:

- Added SPDX-Short-Identifier line (LicenseRef-Keysat-1.0) so
  package metadata scanners can reference a stable name.
- New Section 1 (Definitions): "the Software", "You", "Internal
  Use", "Modifications", "Managed Service" — closes the "is a
  rented VPS internal use?" / "is publicly hosting on Tor a
  managed service?" gaps.
- Internal Use explicitly includes rented compute. Managed
  Service explicitly carves out "your own customers receiving
  signed license keys" so the intended buy-page flow can never
  be misread as forbidden.
- Section 3 (Restrictions) reworded for clarity:
  - (a) "distribute compiled binaries" rather than ambiguous
    "redistribute the source code" — source forks for audit /
    contribution remain permitted under the trailing paragraph.
  - (b) "provide ... as a Managed Service" — clean Elastic-v2
    style phrasing in place of "publicly host a copy that is
    accessible to or operable by parties other than yourself."
  - Public source-code forks on GitHub explicitly permitted.
- Section 4 (Contributions): clarified as a non-exclusive
  license-back, not a copyright assignment. Contributors retain
  ownership.
- Section 6 (Termination): added "destroy or permanently delete
  all copies" on termination + named the survival sections.
- Section 7 (Entire Agreement): added.

For commercial redistribution, resale, or hosted-service rights,
operators still email licensing@keysat.xyz — that's now
explicitly the single contact point at the bottom of the file.

-2. RESTRICTIONS. You may NOT:
+1. DEFINITIONS
-   (a) redistribute the source code, compiled binaries, or derivative works
-       to third parties, whether free of charge or for a fee;
-   (b) sell, sublicense, lease, rent, or otherwise commercialize the
-       software itself (as distinguished from selling licenses to your own
-       software products via an instance of the software);
-   (c) remove or obscure copyright notices or this license text;

+
+2. GRANT OF RIGHTS
+
+   Subject to the restrictions in Section 3, the copyright holder
+   grants You a non-exclusive, worldwide, royalty-free license to:

+
+   (b) compile, install, and run the Software for Internal Use,
+       including operating an instance as Your private licensing

+       free of charge or for a fee;
+
+   (b) provide the Software, or any substantial portion of its
+       functionality, as a Managed Service;
+
+   (c) sell, sublicense, lease, rent, or otherwise commercialize the
+       Software itself (as distinguished from selling licenses to
+       Your own software products through an instance of the
+       Software You operate, which is expressly permitted under
+       Section 2(b));
+
+   (d) remove, alter, or obscure any copyright notices, license
+       text, attribution lines, or this license file embedded in or
+       accompanying the Software.
+
+   Public source-code forks (for example, on GitHub) are permitted
+   provided that the fork carries this license unchanged and does
+   not enable, facilitate, or attempt to circumvent any of the
+   prohibitions above.
+
+
+4. CONTRIBUTIONS
+
+   By submitting any contribution to the upstream project (code,
+   documentation, designs, or other materials), You grant the
+   copyright holder a perpetual, worldwide, non-exclusive,
+   royalty-free, irrevocable license to use, reproduce, modify,
+   relicense, distribute, and incorporate Your contribution as part
+   of the Software or any future version of it, under the terms of
+   this license or any later license the copyright holder adopts.
+   You retain ownership of Your contribution; this Section grants
+   a license-back, not an assignment of copyright.

+   ACTION OF CONTRACT, TORT, OR OTHERWISE, ARISING FROM, OUT OF, OR
+   IN CONNECTION WITH THE SOFTWARE OR ITS USE OR OTHER DEALINGS IN
+   THE SOFTWARE.
+
+
+6. TERMINATION
+
+   This license, and all rights granted to You under it, terminate
+   automatically upon any breach of its terms. Upon termination,
+   You must immediately cease all use of the Software and destroy
+   or permanently delete all copies in Your possession or control.
+   Sections 4 (Contributions), 5 (No Warranty), and 6 (Termination)
+   survive any termination.
+
+
+7. ENTIRE AGREEMENT
