v0.10.0

Added

• ClientOptions.local_mode: turns the client into a no-op — log() returns before buffering, so nothing is retained or sent. Accepts True (always off) or "if_unset_api_key" (off only when no api_key is resolved), which lets the same code run unchanged in dev/test environments without credentials. Honoured by both LogTideClient and AsyncLogTideClient.
• api_url and api_key are optional when local_mode is enabled: ClientOptions(local_mode=True) needs no endpoint, since the client never reaches the network.

Changed

• BREAKING — ClientOptions field order changed: dsn moved to 3rd position and local_mode was inserted 4th. Construction using positional arguments beyond api_url/api_key now binds to different fields — ClientOptions(url, key, 200) previously set batch_size, and now raises DsnParseError. Keyword arguments are unaffected.
• api_url and api_key now default to None instead of "".
• A missing api_url and a missing api_key now raise separate, specific ValueError messages instead of a single combined "Either dsn or api_url + api_key" error.

Internal

• Shared client logic extracted into BaseClient, removing the duplication between the sync and async clients.
• Payload limiting moved to logtide_sdk.payload_limits (apply_payload_limits) and exception serialization to logtide_sdk.serialization, so async_client no longer imports private helpers from client.
