fix(bedrock): preserve dots in model names for Bedrock inference profiles

[superyhee]

Summary

Bedrock cross-region inference profiles use dots in model IDs (e.g. global.anthropic.claude-opus-4-7, us.anthropic.claude-sonnet-4-6).

normalize_model_name() converts dots to hyphens by default, which breaks Bedrock API calls with:

HTTP 400: The provided model identifier is invalid.

This fix adds "bedrock" to the _anthropic_preserve_dots() provider set so that dots are preserved when using the Bedrock provider.

Reproduce

1. Set provider to bedrock with model global.anthropic.claude-opus-4-7
2. Run hermes and send any message
3. Get 400 error: "The provided model identifier is invalid"

Root Cause

_anthropic_preserve_dots() returns False for the bedrock provider, causing normalize_model_name() to transform:

• global.anthropic.claude-opus-4-7 → global-anthropic-claude-opus-4-7

The Bedrock API rejects the hyphenated form.

Test plan

• Verified aws bedrock-runtime converse works with global.anthropic.claude-opus-4-7
• Verified AnthropicBedrock SDK works with the same model ID
• Confirmed hermes conversation works after applying this patch

Thanks for the thorough write-up and the well-scoped fix, @superyhee! This one was already landed on the same day you opened the PR.

This is an automated hermes-sweeper review.

• The identical fix — adding "bedrock" to _anthropic_preserve_dots()'s provider allowlist plus the "bedrock-runtime." base-URL heuristic — was merged via PR [Bug]: Bedrock inference profile model ID dots mangled to hyphens → HTTP 400 "invalid model identifier" #11976 on 2026-04-19 (commit 1cf1016e7).
• run_agent.py line 7260 already contains "bedrock" in the allowlist and line 7272 has "bedrock-runtime." as the URL heuristic — exactly what this PR adds.
• PR [Bug]: Bedrock inference profile model ID dots mangled to hyphens → HTTP 400 "invalid model identifier" #11976 also added a full regression test suite (TestBedrockPreserveDotsFlag, TestBedrockModelNameNormalization, TestBedrockBuildAnthropicKwargsEndToEnd) in tests/agent/test_bedrock_integration.py.

The bug you caught and diagnosed is real and was P1-worthy — it just happened to be fixed concurrently. Closing as implemented on main.
