installer: add explicit asset conflict override

[Kzoeps]

Summary

• Add pnpm install:api --override to replace conflicting declared assets with the incoming bundle.
• Preserve default conflict refusal, full preflight, unchanged-asset skipping, resolver requirements, and existing partial-failure reporting.
• Replacement is complete: omitted optional configuration fields are cleared, not preserved.
• Add offline regression tests, CLI help, operator documentation, and a patch Changeset.

Validation

• pnpm --filter @hypercerts-org/hypercerts-api check passed (generated freshness, lint, types, 280 unit tests).
• node --test api/tests/unit/tooling/installer-core.test.js api/tests/unit/tooling/installer-cli.test.js api/tests/unit/tooling/profile-installer.test.js passed: 36 tests, independently rerun.
• git diff --check passed.
• Changeset validated using an existing lockfile-matching sibling CLI.
• Root pnpm check blocked by missing docs dependency @vitejs/plugin-react.
• Independent review completed; clearing omitted script descriptions is the explicitly approved full-replacement behavior.

Not run

• HTTP runtime tests and live installation; no HappyView uploads performed.
