- 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**
* 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

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.

### Context
The `emails-low-level.tsx` file is where the sending logic of an email
over smtp occurs. It tries to send an email, and if there is an issue it
has logic to mark the email as retryable or not. Then, the
`email-queue-step` itself handles the actual retry efforts based on this
flag and a few other factors (like if max retries have been attempted).
Currently, if an error code isn't explicitly accounted for, it falls
back to being an "unknown error while sending" and is marked as not
retryable.
However, SMTP [defines the 4yz class of error codes as being
retryable](https://www.iana.org/assignments/smtp-enhanced-status-codes/smtp-enhanced-status-codes.xhtml).
### Summary of Changes
We add fallback logic at the end of the `responseCode` specific block to
mark the 4yz class of error codes as retryable. While the message here
is less specific, that is okay since any codes we want to explicitly
account for are handled above it. The main thing here is that these
should be retried.
## Summary
- add a public `defineStackConfig` helper and `StackConfig` type for
nested config authoring
- emit helper-based nested config files from the CLI and local emulator
- update type coverage and e2e expectations for the new `stack.config`
format
## Testing
- pnpm --filter ./packages/stack-shared typecheck
- pnpm --filter ./packages/stack-cli typecheck
- pnpm --filter ./apps/backend typecheck
- pnpm --filter ./apps/e2e typecheck
