Fixes #10002

Summary

RedisContextProvider._redis_search passed the user's message straight into TextQuery / AggregateHybridQuery as the search text. RediSearch reads several punctuation marks as query syntax there — | unions terms, ? is a fuzzy marker, backticks quote exact phrases — so ordinary messages like ps aux | grep python, Why ? or a markdown table reached the engine as malformed grammar (e.g. @content:(ps | aux | | | grep | python)) and raised IntegrationInvalidRequestException: Redis text search failed: ... Syntax error, failing the whole agent run before the model was ever called.

The search text is plain prose, not a query: escape the RediSearch syntax characters with a TokenEscaper configured for them before building either query.

• spaces stay unescaped, so terms keep tokenizing and BM25 scoring works exactly as before
• tag filter values were already escaped via _vector_store's escaper; only the free-text path was exposed
• reproduced at the query-string level: TextQuery(text='ps aux | grep python').query_string() yields '@content:(ps | aux | | | grep | python)' before the fix; after it the terms are escaped and the broken | | shape is gone

Test plan

• new parametrized regression tests in python/packages/redis/tests/test_context_provider_edges.py: all five failing messages from the issue are asserted to produce an escaped query string (no unescaped | ? / | | shapes, escaped chars present), for both the text and hybrid-vector paths — 7 new cases
• 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

Escaping the text before embedding makes hybrid search use different embedding input from stored content, potentially changing retrieval rankings; preserve the original embedding input and add a regression assertion.

What changed in this PR

Addresses #10002 by escaping RediSearch syntax in user messages used for Redis memory retrieval, aiming to prevent punctuation from causing syntax errors that abort agent runs.

Changes:

• Adds a search-text escaper shared by text and hybrid queries, leaving spaces unescaped.
• Adds regression tests for punctuation-heavy messages and escaped text passed to hybrid queries.

File	Description
python/​packages/​redis/​tests/​test_context_provider_edges.py	Adds text-query escaping cases and a hybrid-query regression test.
python/​packages/​redis/​agent_framework_redis/​_context_provider.py	Escapes search text before constructing Redis queries.
