satlink: merged-checkpoint support (export_merged + auto-detect on load); shape-only decoder/bridge construction

merged latent-path checkpoint: RSThinker + LoRA folded + 12-layer bridge in one set of shards

merged pixel-path checkpoint: RSThinker + One-D-Piece ground decoder in one set of shards

satlink: load VLM on meta device and stream shards -- peak host RAM 63.5 GB -> 5.6 GB, load 149s -> 14s; add eager profile= option

satlink: bundle 11 showcase examples (VQA + grounding) with reference recon and answers; JSON-only dumps

satlink: add examples/pipeline.py -- one-shot end-to-end driver with dumpable/resumable satellite stage

satlink: RS-Tokenizer weights (rstok_ground.pt)

satlink: RS-Tokenizer weights (rstok_sat.pt)

satlink: add RS-Tokenizer backend (256x18b, ~114x, ~41dB) alongside One-D-Piece; pixel path only

satlink: public API (Satellite/Ground/GroundVLM), M1000/MUSA support, streaming PNG/BMP encode, acceptance scripts

satlink/ at top level, with train/ (OPSD + data build) included

move satlink_pixel/satlink/ -> satlink/ (it holds BOTH paths, the name misled)

12-layer latent checkpoint; bundled test images + reference; split satellite/ground examples and tests; LHRS + mIoU results

latent path: bridge + modeling_latentvlm + engine support + latent_ground.pt; benchmarked (referring -4.2, VQA +4.6); corrected open-ended VQA scoring

satlink pixel path (deployed+benchmarked) + latent SFT (bridge+LoRA)
