refactor(extension): rename browser extension manifests and API origin to loopover

[JSONbored]

Summary

Renames both apps/gittensory-extension and apps/gittensory-miner-extension manifests' name/description/action.default_title fields, the maintainer overlay's default API origin, the built extension zip's filename/path, and the download link on the site's /extension page — plus the .gitignore entry, production smoke-test target, and a stale CI-comment reference, kept in lockstep so nothing disagrees with the renamed artifact.

New API origin: DEFAULT_API_ORIGIN now points at https://api.loopover.ai (was https://gittensory-api.aethereal.dev). This is a real, already-deployed custom_domain: true route on the same gittensory-api Worker (same binary/D1) as the old domain — not a placeholder — wired live in #4762/#5345. The extension's default is client-side and independently overridable via its options page, so this is a low-risk change distinct from (and doesn't touch) the server's own PUBLIC_API_ORIGIN/PUBLIC_SITE_ORIGIN, which remain on the old domain pending a separate, not-yet-scheduled cutover.

Deliberately unchanged (each tracked elsewhere or genuinely out of scope)

• Directory names (apps/gittensory-extension/, apps/gittensory-miner-extension/) — npm-package-adjacent paths, deferred to the package rename (itself currently blocked on re-planning against a new @loopover npm org).
• The gts_ token wire-format prefix and the GITTENSORY_SESSION_PATTERN identifier — a wire-format/internal-identifier contract, not brand prose.
• The real jsonbored/gittensory GitHub repo-slug string used in a demo mockup.
• The site's own domain (gittensory.aethereal.dev) and PUBLIC_API_ORIGIN/PUBLIC_SITE_ORIGIN — separate, not-yet-cut-over concern.

Follow-up filed separately

Verification surfaced that both extensions' runtime UI (the injected overlay panel in content.js, both options.html pages, and the miner's toolbar badge in opportunity-badge.js) still literally renders "Gittensory" — outside this issue's 4 stated deliverables (manifests, API origin, build script, download link) but a real gap against the epic's broader goal. Filed as its own background task so it can become a small, focused follow-up rather than scope-creeping this PR.

Test plan

• build-extension.mjs runs successfully end-to-end, producing apps/gittensory-ui/public/downloads/loopover-extension.zip with the correctly-renamed manifest inside.
• Full npm run test:ci gate green (typecheck, coverage, engine-parity, mcp/miner builds+packs, UI lint/typecheck/test/build).
• npm audit --audit-level=moderate — 0 vulnerabilities.
• Confirmed via targeted test runs (extension-auth, extension-content, miner-toolbar-badge — 18 tests) that no assertion depended on the old brand string or old zip filename, so no test edits were needed.
• Regenerated packages/gittensory-miner/docs/env-reference.md (unrelated drift surfaced by rebasing onto a moved origin/main — a new upstream env var reference needed a doc regen).
• Repo-wide sweep confirming every remaining gittensory-extension/gittensory-miner-extension reference is a directory-path reference, correctly left alone per this issue's own stated boundaries.

Closes #5329.
