fix(core): commit generated migration for session directory index #239

Contexto

unit (linux) and unit (windows) are currently red on dev itself (confirmed on the latest dev commit, run https://github.com/alltomatos/opencode/actions/runs/34911995346/job/104201311221), from test/database-migration.test.ts > "declared schema has no ungenerated migrations". Blocks CI on every open PR regardless of what it touches — including #234 and #237.

Root cause

perf(core): add composite index on session(directory, time_created, id) (closes #229) (commit 5372b2ed3f) added an index declaration to packages/core/src/session/sql.ts:

index("session_directory_time_created_id_idx").on(table.directory, table.time_created, table.id),

but never ran the migration generator, so the declared Drizzle schema and the committed migration/snapshot (schema.json, schema.gen.ts, migration.gen.ts) diverged. The check script's own error names the fix: "Run bun script/migration.ts from packages/core."

Fix

Ran bun script/migration.ts from packages/core (no manual edits to any generated file) and committed the result: a new migration file, and the regenerated schema.json/schema.gen.ts/migration.gen.ts.
