chore: release 0.7.0 rather than 0.6.1 (#126)

There are 15 feature commits since v0.6.0 — the mobile foundation, country
filters, cost receipts, scenario intelligence, the notify list and private
pasted-prompt estimation. A patch number would misstate that, and the Zenodo
DOI minted from this tag records the version permanently.

-these commits came after it, so they are recorded here rather than folded into

+## [0.7.0] — 2026-08-30
+
+Everything below landed after `v0.6.0` was tagged at `fd54a49`. A minor rather
+than a patch release: the mobile foundation, country filters, cost receipts,
+scenario intelligence, the launch notify list and private pasted-prompt
+estimation are all new capability, not repairs.
+
+This is also the first release the project can be **cited** by. `CITATION.cff`
+and `.zenodo.json` mean the tag is archived and given a DOI, so a cost estimate
+published elsewhere can point at the exact version of the engine and the price
+catalog it relied on.
