## Summary by CodeRabbit
* **Bug Fixes**
* Improved system reliability by correcting internal guidance for
user-data handling, preventing unsafe retrieval patterns and reducing
risk of incorrect or incomplete user responses.
* **Chores**
* Tightened AI system prompts with stricter runtime validation and
selection rules to ensure user queries return accurate, privacy-safe
results.

- Added new internal API endpoint for documentation tools, allowing
actions such as listing available docs, searching, and fetching specific
documentation by ID.
- Updated environment configuration to support optional internal secret
for enhanced security.
- Refactored existing search functionality to utilize the new docs tools
API instead of the previous MCP server.
- Improved error handling and response parsing for documentation-related
requests.
- Expanded documentation to clarify the relationship between the new
tools and existing API functionalities.
This update streamlines the documentation access process and enhances
the overall developer experience.

## Summary by CodeRabbit
* **New Features**
* Non-stream AI responses now include a consolidated finalText for
clearer answers.
* Added an internal docs-tools HTTP API to power doc listing, search,
and fetch with optional header-based access control and configurable
service origin.
* **Refinement**
* Consolidated multiple doc tooling paths into a single question-focused
flow; backend now routes to the unified docs-tools endpoint.
* **Documentation**
* Updated guides and knowledge base to describe the new docs query flow
and optional env configuration.

## Summary by CodeRabbit
* **New Features**
* Risk scoring now tracks and reports counts of recent signups that
share a normalized email (with configurable limit), exposing this as
part of signup-risk statistics.
* **Performance**
* Added a database index and migration to speed up recent-signup
queries, improving risk assessment responsiveness.

The ClickHouse connected_accounts table is keyed by (project_id,
branch_id, user_id, provider, provider_account_id), so updating
providerAccountId in place on ProjectUserOAuthAccount orphaned the old
CH sort-key row: the sync re-emitted the row under the new key while the
old key sat untouched with no tombstone, and FINAL couldn't collapse
them. verify-data-integrity would then report a row count mismatch for
connected_accounts.
Record a delete tombstone for the old row state before the update runs,
so the sync pipeline marks the stale sort key as deleted.

The custom-base-port and db-migration-backwards-compatibility workflows
were running cron jobs with `with-env:dev` instead of `with-env:test`,
causing ClickHouse sync mismatches in verify-data-integrity.

## Summary by CodeRabbit
* **Chores**
* Streamlined CI test workflows to standardize background cron job
startup for more consistent test runs.
* **Tests**
* Improved end-to-end test reliability by aligning background process
behavior across suites.
* **Bug Fixes**
