Count OpenCode v2 usage

[btsouth]

OpenCode 2.x writes messages to session_message and session_v2 instead of message and session, so Agent Pulse stopped counting OpenCode and OpenCode Go usage after the upgrade.

The OpenCode scan now reads whichever tables exist. v2 rows go through the same opencode_record path, so routing and pricing match v1. OpenCode v2 copied v1 messages into the new table with their original ids, so a message in both tables still counts once.

Releases 1.10.5.

Checks:

• python3 -m unittest discover -s tests: 237 tests OK, including four new OpenCode v2 cases (v2-only database, an id present in both tables, the Go route, and an in-place update under WAL)
• Read-only check against a real OpenCode database: all 9,262 messages present in both tables have the same route and token counts, and 50 messages exist only in v2

Summary by CodeRabbit

• Bug Fixes

  • OpenCode usage tracking now includes assistant-message tokens from both v1 and v2 history.
  • Messages carried over between versions are counted once, preventing duplicate usage totals.
  • Usage updates are reflected during scans, including when OpenCode data changes while the app is running.

• Release

  • Updated the release version to 1.10.5.
