[DOCS] Missing `deepStrictAssert` deprecated notation in README

[kakasoo]

Documentation

Description

src/functions/DeepStrictAssert.ts has a @deprecated JSDoc annotation, but the README.md Runtime Functions section does not show a deprecated notation. Users may unknowingly use the deprecated function in new code.

Current State

• Code (src/functions/DeepStrictAssert.ts:13): @deprecated Use {@link deepStrictPick} instead.
• README: deepStrictAssert is described as a regular function without any deprecation notice

Fix

In the README's Runtime Functions table or section:

1. Add deprecated notation to deepStrictAssert
2. Add migration guide recommending deepStrictPick usage

Test Requirements

Since this is a documentation change, code tests are not required, but verify that the build does not break:

npm run build:test && npm run test
