Fixes #9966

Summary

RedisHistoryProvider treated redis_client, redis_url and credential_provider as strictly mutually exclusive, so a working caller-owned client passed together with a stray redis_url (or credential provider) raised ValueError: redis_client, redis_url, and credential_provider are mutually exclusive at construction instead of using the injected client.

The Redis vector-store constructors already follow the intended behavior: they bypass URL, credential and host settings whenever redis_client is supplied. This gives the history provider the same precedence:

• the mutual-exclusion check only rejects multiple non-client connection sources
• the host is required check only applies when the provider will build a client itself
• the injected client stays caller-owned (_owns_client=False) and nothing about it is validated beyond the existing type / decode_responses checks
• provider-level storage settings (key scope, retention) keep applying
• docstrings and the Raises block updated to state the precedence

Test plan

• new test_borrowed_client_takes_precedence_over_other_connection_sources (parametrized over redis_url / credential_provider+host): the injected client is used and no mutual-exclusion error is raised — replaces the test that pinned the old rejection
• test_url_and_credential_stay_mutually_exclusive_without_client keeps the no-client case covered (already existed as test_both_url_and_credential_raises)
• pytest tests -m 'not integration' in python/packages/redis — 337 passed, 58 deselected (integration), no new failures
• ruff check / format clean on both changed files

🟡 Changes recommended

Query escaping also alters the text passed to aembed(), potentially changing hybrid rankings; embeddings should use the original stripped text, with regression coverage asserting that input.

• Escape query text only for Redis, not embeddings · New

What changed in this PR

This PR aligns RedisHistoryProvider with Redis vector-store behavior by prioritizing caller-owned clients, addressing #9966. It also adds query-syntax escaping to Redis context searches.

Changes:

• Prefer injected history clients over other connection settings while preserving ownership and compatibility checks.
• Escape user text before constructing text and hybrid search queries.
• Add regression tests for client precedence and query escaping.
