Commit Message

Fix Anthropic provider tool result encoding for multi-turn conversations (#94)

Resolves critical bugs preventing tool calling from working with
Anthropic models:

1. Transform :tool role to :user - Anthropic API only accepts "user" or
"assistant"
   roles, not "tool". Tool results must be sent in "user" messages.

2. Encode tool_result content blocks - Previously returned nil, causing
content to be
   filtered out. Now properly encodes with tool_use_id and serialized
output.

Changes:
- lib/req_llm/providers/anthropic/context.ex: Add role transformation
and tool_result encoding
- test/providers/anthropic_test.exs: Add multi-turn tool calling test
- test/req_llm/integration/tool_result_encoding_test.exs: Add
comprehensive provider-agnostic
  test suite for tool result encoding (7 tests covering edge cases)

All tests pass. Multi-turn tool calling now works correctly with
Anthropic models.
