fix: add missing DetailedChargeState value; recommend against tesla-protocol dependency

AGENTS.md

@@ -9,6 +9,7 @@ This file is the project's committed home for project-intrinsic agent knowledge:
 - `tests/` files are plain scripts (`if __name__ == "__main__"`), not pytest-based - pytest would collect zero tests here. Run each directly, e.g. `uv run python tests/test_config_events.py`.
 - `pyproject.toml` has a `[tool.mypy]` config but no dev-dependency group declares mypy, so `uv sync` alone won't install it. CI installs it ephemerally via `uv run --with mypy mypy teslemetry_stream`.
 - `Signal` in `const.py` tracks <https://api.teslemetry.com/fields.json>; the config route rejects names it does not know with `fst_err_validation`. Fields the API has retired are not rejected - it accepts the request and names them in a top-level `ignoredFields` list - so the library can lag the published list without breaking.
+- The `TeslemetryEnum` value tables in `const.py` (`ShiftState`, `BMSState`, `DetailedChargeState`, etc.) are hand-maintained against the `tesla-protocol` PyPI package's proto enum descriptors (`tesla_protocol.telemetry.vehicle_data_pb2`), not derived from it at runtime: nearly every table matches its proto enum byte-for-byte under simple prefix-stripping, but `tesla-protocol` requires `protobuf` + `googleapis-common-protos` as runtime dependencies, which is disproportionate for sourcing ~40 static string lists in a library whose only current dependency is `aiohttp` and whose consumers (Home Assistant integrations) are sensitive to protobuf version pinning. `ChargeState` is the one table that does not match the proto at all (already commented in `const.py` - deprecated field). `tests/test_enum_tables.py` pins the tables most likely to drift against the proto names actually observed in `tesla-protocol` 1.4.0, as a manual re-check aid, not a live comparison.
 - Adding a new streamable field (e.g. from an upstream `teslamotors/fleet-telemetry` `Field` enum addition): give it a `Signal` entry in `const.py` in alphabetical order by the Python constant name, but append its `listen_<Field>` method to the *end* of `TeslemetryStreamVehicle` in `vehicle.py`, not alphabetically re-inserted - the method order there is chronological-by-addition (see the tail of the class), not sorted. Pick `make_int`/`make_float`/`make_bool`/`make_dict` by matching the closest existing field of the same shape (unit suffix, boolean vs measurement, etc.); there is no per-field firmware-version metadata tracked anywhere in the library, so omit it.
 - Config responses are shaped inconsistently: success is flat, `{"updated_vehicles": n}` plus `ignoredFields` when some were dropped, while errors are wrapped, `{"response": null, "error": ...}`. Do not look for `updated_vehicles` under `response`; that lookup silently never matches.
 - `update_config` funnels every caller through one per-vehicle single-flight flush (`TeslemetryStreamVehicle._flush`): the first caller starts it, later callers merge into the same pending config and await it rather than starting their own PATCH. This exists because a batch of listeners scheduled at once (e.g. HA integration setup) must produce one PATCH, not one per listener - see `tests/test_batch_retry_storm.py`. A body-shaped error (`{"error": ...}`) is terminal for that batch: it is not replayed, but the pending config is kept for the next explicit `update_config` call. A transport-level failure (`aiohttp.ClientError`/timeout) gets one bounded retry inside the same flush. `tests/test_config_update.py` covers the response-shape handling.
