cli: migrated v1 sessions from non-git dirs missing from session list #52919

Description

Migrated v1 sessions are missing from the project-scoped session list when their directory is not a git repo.

After upgrading from V1 (1.14.32-1.18.32) to 2.0.22, the data migration reports completed and no data is lost, but sessions created in non-git directories keep the V1 project_id = "global". V2 scopes /sessions and opencode session list to the current project, and V2 creates a separate project entry for that same directory, so those sessions get filtered out.

Affected in my case: 30 of 37 migrated sessions (/home/nicola 23, ~/blender 6, ~/trading 1). Sessions from git repos (salon-bot, TradingAgents, transpotec) are unaffected and list normally, so this looks specific to the global project id.

Workaround: transcripts are intact and reachable via Ctrl+O (recent sessions and projects) or opencode -s <sessionID>.

Expected: either the migration should re-map project_id from the stored session_v2.directory/path, or the project-scoped list should include global-project sessions whose directory matches the current location.

OpenCode version

2.0.22 (channel: latest), upgraded from v1 1.14.32-1.18.32

Steps to reproduce

1. In V1 (1.14.x-1.18.x), run OpenCode from a directory that is not a git repo and create a few sessions.
2. Upgrade to V2 (2.0.22) and start it once so the data migration completes.
3. opencode api get /api/experimental/migration/v1 -> {"status":"completed"}
4. cd into that same directory and run opencode session list -> only sessions created after the upgrade are listed, the v1 ones are missing.
5. opencode api get "/api/session?limit=100&directory=<that directory>" -> the v1 sessions are returned.
6. Read-only DB check: SELECT project_id, count(*) FROM session_v2 GROUP BY project_id -> the v1 sessions are counted under global.

Also note: in step 4, pressing Ctrl+O in the TUI does show them, so the sessions are reachable but not listed in the normal session view.
