chore(release): 9.0.0 (#186)

chore(release): 8.2.0 (#185)

## Added

- New v2 export methods in `ExportApi`: `export_signals_v2`,
  `run_export_signals_v2`, and `export_signals_v2_bytes`.
- New CLI script `exabel.scripts.export_signals_v2` that runs a v2 signal
  export and writes the raw server response to disk. Output format is
  selected by the `--filename` extension (`.csv`, `.xlsx`, `.json`,
  `.feather`, `.parquet`).
- New optional dependency group `export`. Install with
  `pip install 'exabel[export]'`.

## Changed

- `pyarrow` is required for `export_signals_v2` and `run_export_signals_v2`.

## Deprecated

- `signal_query_v2` and `run_signal_query_v2` are deprecated; use
  `export_signals_v2` and `run_export_signals_v2` instead.
- `run_query_bytes` with `file_format="pickle"` is deprecated.

## Removed

- The v2 export endpoint no longer accepts `output_format="pickle"`.

chore(release): v8.1.0 (#184)

## Added

- v2 export signals API in `ExportApi`, with support for `DerivedSignal` and
  `Column` arguments in `signal_query()` / `batched_signal_query()`.

## Changed

- Prepared timestamp handling for pandas 2.x: new resolution-agnostic datetime
  conversion helpers used by `TimeSeriesApi` and related data classes.
- Removed usage of pandas APIs deprecated in 2.x across `ExportApi`,
  `FileTimeSeriesParser`, and the `check_company_identifiers_in_csv` script.
- Internal code cleanups from expanded linter rule sets; no behavioral changes.
- Require grpcio-tools >=1.78.0
