feat(content): add cosmos_miri pool member (Carina mid-infrared pan)

Operator wanted more Cosmic Cliffs footage and a different-color rendering.
Keeps the NIRCam flythrough as the cosmos primary and adds ESA/Webb weic2205c
("Pan of the Carina Nebula, combined NIRCam + MIRI") as a new cosmos pool
member — the same Carina towers in the muted gray/teal/gold MIRI mid-infrared
palette, distinct from the iconic orange/blue flythrough.

- POOLS["cosmos"] grows 4 -> 5 (cosmos, cosmos_miri, galaxies, hudf, xdf);
  primary unchanged.
- META + LABELS authored (nebula/star/distance, salience-gated); affect inherits
  the cosmos scale vocabulary.
- manifest.json regenerated (19 -> 20 clips).
- Source: 4K master, text-free/human-free, trim 4-26s (clears the fade-from-
  black), 1 s crossfade-loop (~21 s) -> 1080p base + 4K master (gitignored).
- docs/content-candidate-pool.md updated (cosmos pool of 5 + sourcing note).

271 passed, 2 skipped.
