Documentation-only PR (+52/-44, CHANGELOG.rst only) that reorganizes the 0.45 "New Features" section into sub-sections (Quantization, Megatron Framework, Datasets & Calibration, Misc) for readability, moves the Deprecations block above Bug Fixes, and updates release dates (0.46 → 2026-08-xx, 0.45 → 2026-07-02).

I cross-checked the reorganized list against the original flat list: every New Features entry is preserved and correctly re-categorized. The old changelog contained two near-duplicate Megatron-Bridge PTQ entries; the new version sensibly consolidates them into a single expanded entry — a net improvement, not a content loss.

No code changes, so no tests are warranted. No licensing files touched (only CHANGELOG.rst). No prompt-injection attempts in the untrusted PR content. Straightforward and correct.
