Ricardo db10d9cfbf fix(og): batch spawning to prevent OOM during watcher rebuilds ...

Full OG regeneration (2,350 images) OOM-kills when the Eleventy watcher
is running (~1.8 GB RSS), leaving only ~1.2 GB headroom in the 3 GB
container. WASM native memory from Satori/Resvg grows beyond what GC
can reclaim within a single process.

Solution: spawn og-cli in batches of 100 images. Each invocation exits
after its batch, fully releasing all WASM native memory. Exit code 2
signals "more work remains" and the spawner re-loops. Peak memory per
batch stays under ~500 MB regardless of total image count.

Also seed newManifest from existing manifest so unscanned entries survive
batch writes.
