test(utils): add unit test suite for primitive to bytes encoding helper

[gcoinstash-cmd]

Summary

Adds isolated unit tests for key/primitive type string encoding to bytes:

• Bytes pass-through invariance
• String to UTF-8 conversion
• Numeric and Boolean primitive casting
• None handling

---

Note

Low Risk
Test-only addition with no production code or runtime behavior changes.

Overview
Adds tests/test_safe_str_encoding.py, a new pytest module that defines a local safe_str_encode helper and exercises primitive-to-bytes encoding behavior.

Coverage includes bytes pass-through, UTF-8 encoding of strings, casting of int/float/bool via str() then encode, and None returning None. The helper is defined in the test file only; it does not wire into existing production utilities in this diff.

Test the production encoder instead of a local copy

Every assertion calls the function defined in this test module, so the suite cannot detect regressions in redis-py's actual encoding code. It also establishes expectations that conflict with redis._parsers.encoders.Encoder.encode, which raises DataError for both bool and None; changes or breakage in that production path will leave all four tests green. Import and exercise the intended production helper rather than reimplementing it in the test.

Tests skip production encoding helper

Medium Severity

safe_str_encode is defined in this test module instead of being imported from the library. The suite only asserts against that local copy, so it never exercises Encoder.encode or redis.utils and cannot catch production encoding regressions.
