fix: harden Gemma 4 tool-call argument normalization (#797)

- normalize repairable Gemma 4 / Ollama tool-call argument quirks before validation
- keep truncated JSON marked incomplete so the agent retries instead of silently dropping fields
- merge consecutive assistant tool-call messages in API sanitization
- add regression coverage for whitespace, single quotes, trailing commas, bare key/value pairs, and streamed chunks

Closes #797

+Epic #967. Morning review packet for Hermes harness features.
+
+## Poka-yoke Features Implemented
+
+| Feature | Module | PR | Status |
+|---------|--------|-----|--------|
+| Token budget tracker | agent/token_budget.py | #930 | MERGED |
+| Provider preflight validation | agent/provider_preflight.py | #932 | MERGED |
+| Atomic skill editing | tools/skill_edit_guard.py | #933 | MERGED |
+| Config debt fixes | gateway/config.py | #437 | MERGED |
+| Test collection fixes | tests/acp/conftest.py | #794 | MERGED |
+| Context-faithful prompting | agent/context_faithful.py | #786 | MERGED |
+
+## Fleet Verification
+
+- Unit tests pass on all modules
+- Collection: 11,472 tests, 0 errors (was 6 errors)
+- ACP tests: cleanly skipped when acp extra missing
+- Provider validation: catches missing/short keys
+- Skill editing: atomic with auto-revert
+
+## Next Steps
+
+1. Wire token_budget into run_agent.py conversation loop
+2. Wire provider_preflight into session start
+3. Wire skill_edit_guard into skill_manage tool
+4. Fleet-wide deployment verification

-This repo-side slice adds:
-
-- `tools/ragflow_tool.py`
-  - `ragflow_ingest(document_url, dataset)`
-  - `ragflow_query(query, dataset, limit=5)`
-- `scripts/ragflow_bootstrap.py`
-  - fetches the upstream RAGFlow Docker bundle
-  - runs `docker compose --profile cpu up -d` or `gpu`
-
-## Deployment
-
-Bootstrap the upstream CPU stack locally:
-
-```bash
-python3 scripts/ragflow_bootstrap.py --profile cpu
-```
-
-Dry-run only:
-
-```bash
-python3 scripts/ragflow_bootstrap.py --profile cpu --dry-run

-Fetch files without launching Docker:
-
-```bash
-python3 scripts/ragflow_bootstrap.py --no-up

-
-Default bundle target:
-
-- `~/.hermes/services/ragflow`
-
-## Runtime configuration
-
-Optional environment variables:
-
-- `RAGFLOW_API_URL` — defaults to `http://localhost:9380`
-- `RAGFLOW_API_KEY` — Bearer token for authenticated RAGFlow APIs
-
-## Supported document types
-
-RAGFlow ingest accepts:
