Ensure virtual tables invalidate cached schema metadata and reload it when a schema change (e.g., ALTER VTABLE) is detected. This prevents stale schema references and query errors after structural updates.

* Update 09-error-code.md
* Update 09-error-code.md
* fix: remove usless case
* feat(stream): extract original table data in source scan task
Implemented functionality in the source task to extract data
corresponding to the virtual table from the original table using WAL.
The extracted data is then sent to the downstream merge task for further
processing.
* feat(stream): multi-way merge using loser tree in virtual merge task
Implemented multi-way merge in the merge task using a loser tree to
combine data from multiple original table into a single virtual table.
The merged virtual table data is then pushed downstream for further
processing. Introduced memory limit handling during the merge process
with configurable behavior when the memory limit is reached.
* fix(test): remove useless cases

Introduce the `true for` syntax to allow users to specify the minimum
duration for event and state windows. Add corresponding tests to
validate the feature. Updated the user manual with usage instructions.
- Introduce new syntax to specify notification type and destination address
- Collect relevant event information during window computations
- Implement websocket-based notification delivery to the specified address
Add the AUTO keyword, which allows automatic determination of the
INTERVAL OFFSET based on the WHERE condition. It simplifies usage by
allowing users to rely on the system to infer the correct offset
without manual specification.
To address the issue of non-unique identifiers for query tasks, a unique
client ID (cid) is now generated during client initialization. This cid
is included in every task message sent to the server. The server will
use a composite key of <qid, cid, tid, eid> to uniquely identify each
query task.
