feat: dataset-mirror — 100x faster ingest by bulk-cloning community SFT mixes

User: '10 GB/hr is bullshit. โหลดหนังโป๊ยังได้เยอะกว่า'.

The bottleneck is NOT bandwidth — HF's 128 commits/hr cap times 5 sibling
datasets = 640/hr aggregate. We were under that cap (~150/hr).

The bottleneck is per-row processing: dataset-enrich.sh streams each row,
runs schema normalization, dedup-checks, and rewrites in our format. Each
ingest pass = maybe 1-5K NEW rows after dedup → 1 small commit. Slow.

dataset-mirror.sh does the OPPOSITE: pulls the entire parquet shard from
a popular community SFT mix (e.g. teknium/OpenHermes-2.5 = 1M rows), and
uploads each shard as one commit at mirrors/<slug>/<file>. The conversion
to our schema happens at TRAIN TIME instead of INGEST TIME.

30 sources curated for first cycle:
Massive SFT: OpenHermes-2.5, ultrachat-200k, OpenOrca, SlimOrca-Dedup,
no-robots, dolly-15k, Open-Platypus, OpenMathInstruct-2
Code: Magicoder-OSS, Magicoder-Evol, CodeAlpaca, Evol-Code-80k,
starcoder2-self-oss, m-a-p/CodeFeedback, smoltalk
Reasoning: orca-math-200k, MetaMathQA, proof-pile-2, finemath
Tool: xlam-fc-60k, orca-agentinstruct-1M
Conversational: lmsys-chat-1m, HelpSteer3, hh-rlhf
Multilingual: aya-dataset, aya-collection
Curated: magpie-ultra, magpie-pro-300K, capybara-dpo-7k

Each source typically 100MB-5GB of parquet. 30 sources × ~1GB avg ×
1 commit/file = ~30 GB landing in 1-2 hours, then ~5M+ training pairs
available immediately. Stamp file (~/.surrogate/state/dataset-mirror-stamps.json)
makes this idempotent — re-runs skip already-mirrored sources.

Boot-time kickoff so first batch lands immediately on Space rebuild.
