Prepare the reviewed bilingual v1.38.0 catalog from the merged product range. Document independent search, protocol recovery, desktop management and link menus, update relaunch, model image controls, and restored session actions.

Include the DeepSeek configuration upgrade and explicit recovery/downgrade limitations. Cite integrated contributor work through its merged PR.

Verification: Catalog validation, release-note tests, required Notes PR checks, rendered bilingual content review, and publication privacy scan passed. This Notes commit follows the release-test corrections and defines the candidate for exact-SHA main-v2 CI.
