feat: add Stronkter catalog blocks (#570)

## Problem

The Catalog did not include the four prompt-matched Stronkter one-shot HyperFrames projects, and registry metadata only supported a plain author string, so there was no structured way to show creator attribution or the original generation prompt on generated catalog pages.

## What this fixes

- Adds four Catalog blocks matching the provided prompts, in order:
  - `north-korea-locked-down`
  - `apple-money-count`
  - `nyc-paris-flight`
  - `goonvpn-youtube-spot`
- Attributes each block to [Stronkter](https://x.com/Stronkter).
- Stores and renders the original source prompt for each generated catalog page.
- Adds a local realistic map plate for the North Korea block so rendering does not depend on live map tile requests.
- Extends registry item metadata/schema with `authorUrl` and `sourcePrompt`.
- Updates catalog page generation to read items from `registry/registry.json`, keeping generated docs aligned to the public registry manifest.
- Ignores normal browser media preload `net::ERR_ABORTED` request failures for media assets during `hyperframes validate`, while preserving failures for real missing assets.

## Root cause

The imported projects are Catalog-ready compositions, but the registry/docs pipeline did not have first-class source-prompt or linked-author fields to expose creator credit on generated MDX pages. The audio-backed compositions also surfaced a validation edge case: Chrome can report aborted media preload requests as `net::ERR_ABORTED` even when the audio file exists and playback is valid.

## Verification

### Local

- `bun run --filter @hyperframes/cli test src/commands/validate.test.ts`
- `bun run --filter @hyperframes/core test src/registry/types.test.ts`
- `bun run sync-schemas:check`
- `bunx oxlint packages/cli/src/commands/validate.ts packages/cli/src/commands/validate.test.ts packages/core/src/registry/types.ts packages/core/src/registry/types.test.ts scripts/generate-catalog-pages.ts`
- `bunx oxfmt --check ...` on changed source, registry, docs, and composition files
- `git diff --check`
- `bun packages/cli/src/cli.ts lint` and `validate` against temp installed projects for all four blocks
- Lefthook pre-commit: lint/format/typecheck on the initial commit, plus format on the amend
- Lefthook commit-msg: commitlint

### Browser

- Exercised all four blocks through HyperFrames preview routes with `agent-browser`.
- Captured playback screenshots and WebM recordings for:
  - `north-korea-locked-down`
  - `apple-money-count`
  - `nyc-paris-flight`
  - `goonvpn-youtube-spot`

## Notes

- The zip also contained unrelated project directories, but this PR intentionally includes only the four prompt-matched Catalog blocks requested here.
- The imported one-shot compositions may trigger the existing large-composition lint warning, but there are no lint errors and runtime validation passes.
