Correct BF16 source size (V3 carryover 1.3 TB → V4 ~600 GB)

README: license=mit, honest calibration disclosure, AIME wall-clock vs decode disambiguated, absolute doc links

License: correct frontmatter to MIT (matches upstream DeepSeek-V4-Flash)

README: scrub DSV4-Pro mentions; replication template now architecture-agnostic

README: humble rewrite (no emojis, no superlative framing)
