feat(api): support native server batch overloads

[albert20260301]

Summary

• pin altertable-client-specs to v0.13.0
• overload track, identify, and alias to accept caller-supplied payload arrays
• submit each supplied array as one request without a client-side size cap
• document the behavior and cover a 101-payload track pass-through case plus identify/alias array routing

Impact analysis

The existing scalar server APIs retain their payload construction and validation. Passing an array as the first argument now posts that exact array to its corresponding endpoint, matching the v0.13.0 server-tier contract without introducing separate *_batch APIs or a maxBatchSize setting.

The equivalent server-tier behavior is being checked in the other reachable product analytics SDKs. Web and mobile SDKs instead use the new 20-payload per-endpoint cap.

Validation

• python3 -m py_compile src/altertable/client.py tests/test_altertable.py
• git diff --check
• Full pytest and Ruff validation are deferred to repository CI because this environment has no Poetry, pip, pytest, or Ruff installation.

@redox could you review this?

You requested the v0.13.0 downstream updates. CI is green. The main review focus is the server-tier contract: batch methods no longer impose device queue limits and preserve each payload's order and fields.
