Table existence checks should not depend on listing every table or
searching only the first 100 names. Use a direct lookup for `name in db`
and implement `table_exists(table_id)` on synchronous local connections,
matching the remote and asynchronous APIs. Native namespace connections
use their initialized Rust connection for existence checks; custom
namespace clients retain their existing callback. Missing tables return
`False`; other lookup errors propagate.
```python
if "events" in db:
db.drop_table("events")
exists = db.table_exists(["analytics", "events"])
all_names = list(db.list_tables())
```
Clarify that `.tables` contains one page and update deprecation guidance
with safe replacements. Add regression coverage for lookups beyond the
first page, nested namespaces, native and custom namespace clients,
missing tables, permission errors, and lookups that do not list tables.
Include an unpublished draft for the table-management guide until the
new SDK support ships.
