Bump plugin version to 0.2.9

[dimavrem22]

Executive Summary

Bumps the Claude Code integration from 0.2.8 to 0.2.9 for the next patch release and makes the hosted-voice live request explicit about both durable action fields.

Description

Updates package metadata, the exported runtime version, and MCP server identification so every Claude Code version surface reports 0.2.9. The hosted-voice live instruction now requires the unique SMS marker in both the action title and details, while retaining the strict persisted-action and delivered-SMS assertions.

Reason

The recently merged non-interactive bootstrap capability needs a new patch version for distribution and runtime identification. Explicit action-field values remove model ambiguity observed in the live hosted-voice gate.

Decisions

• Patch release: Version surfaces increment by exactly 0.0.1.
• Version consistency: Package and runtime-reported versions remain synchronized.
• Test integrity: The live test still requires one open SMS action with the current marker and verifies the resulting post-call SMS; only its spoken input is more explicit.

Testing

• pytest -q --ignore=tests/contract: 436 passed and 23 live-only tests skipped.
• pytest -q tests/test_live_voice_contract_helpers.py: 10 passed.
