Remote Python connections inherited the unsupported-operation stubs for `namespace_exists` and `table_exists`, so both raised `NotImplementedError` even when namespace and table operations worked. Add the missing remote overrides, async methods, and PyO3 bindings using the existing namespace describe and table open paths. Only an explicit not-found result returns `False`; permission, transport, and server errors propagate. This preserves authentication, dynamic headers, retries, and nested namespace handling, and rechecks cached tables before reporting that they exist. The async namespace helper also recognizes native `NamespaceNotFound` errors so missing local namespaces return `False`. The table and namespace guides document Python remote support and distinguish it from the unsupported `exists` routes used by direct REST namespace clients. Validation: - All 40 focused regression cases pass, covering successful and missing lookups, local and remote namespaces, dynamic headers, permission/server errors, invalid table identifiers, and cached tables that disappear. - The original inherited stubs reproduce the reported `NotImplementedError`; the local namespace regression reproduced the native missing-namespace `RuntimeError` before its fix. - Full remote connection suite: 255 passed. Local namespace tests: 14 passed. - `cargo clippy --quiet -p lancedb-python --features remote --lib`, `cargo fmt --all`, Python Ruff lint, and Python formatting checks pass. - Root `ruff check .` reports 48 existing errors in documentation examples under `docs/web-tests`; the Python subtree passes and those unrelated files are unchanged.
