`window.screen` and `window.history` are accessor properties on
`Window.prototype`, so `Object.getOwnPropertyDescriptor(window,
X)?.value` returned undefined in real browsers, causing `start()` to
short-circuit and never capture or send any $page-view / $click events.
Read the globals directly instead; the jsdom-based regression test pins
the accessor-descriptor shape so this can't silently come back.

## Summary by CodeRabbit
* **Tests**
* Added a new test suite verifying event batching, timing, page-view and
click event capture, and client-side navigation behavior using simulated
timers and DOM environment.
* **Bug Fixes**
* Improved event tracker reliability by changing how browser screen and
history are read, yielding more consistent detection of screen
dimensions and navigation for analytics capture.

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

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.
