chore: rebrand to GSD-redux/get-shit-done-redux

Mirror of code, issues, and PRs from the upstream gsd-build/get-shit-done,
which appears compromised or abandoned (maintainer unreachable since
2026-04-01; $GSD token linked to rug-pull).

- Adds rebrand notice block at top of English README
- Removes $GSD token badge and @gsd_foundation X badge (keeps Discord)
- Renames npm packages: get-shit-done-cc -> get-shit-done-redux,
  @gsd-build/sdk -> @gsd-redux/sdk
- Updates all repo URLs across docs, workflows, package.json, bin/
- Updates ci@gsd-build -> ci@gsd-redux in workflow git identities
- Leaves CHANGELOG and .changeset/* alone (historical, time-stamped)

 - `GSDTools` now routes through the **SDK Runtime Bridge Module** (`sdk/src/query-runtime-bridge.ts`). Native registry dispatch is preferred; subprocess fallback is explicit policy (`allowFallbackToSubprocess`) and can be disabled for strict SDK-only execution.
 - `strictSdk` mode fails fast when a command has no native adapter, making SDK publish/readiness checks deterministic.
