Deprecate deepseek-chat / deepseek-reasoner; add v4 models

Browse source 
Per https://api-docs.deepseek.com/quick_start/pricing, DeepSeek retires
the legacy slugs `deepseek-chat` and `deepseek-reasoner` on 2026-07-24
(15:59 UTC). During the grace period they transparently route to
deepseek-v4-flash (non-thinking and thinking modes respectively); after
2026-07-24 they will be inaccessible.

Tag the four legacy entries (with and without provider prefix) with
deprecation_date 2026-07-24 and add canonical entries for the two
current models:

  deepseek-v4-flash : $0.14 in / $0.28 out per 1M ($0.0028 cache hit),
                      1M ctx, 384K max output
  deepseek-v4-pro   : $1.74 in / $3.48 out per 1M ($0.0145 cache hit),
                      1M ctx, 384K max output (standard pricing — the
                      75% promo discount ends 2026-05-31)

Both support thinking + non-thinking modes, function calling, and
prompt caching.
