PRATHAMESH75 034eadb326 perf(state): index assistant tool-call rows for Insights queries
InsightsEngine._get_tool_usage and _get_skill_usage scan messages for
role='assistant' AND tool_calls IS NOT NULL, but no index aligns with
that predicate, so SQLite scans the full messages table on a large
state.db. Add a partial index over exactly those rows.

role and tool_calls are base columns in the messages table, so the index
lives in SCHEMA_SQL (created on both fresh and existing databases via the
executescript on every open) rather than DEFERRED_INDEX_SQL.

Adds schema regression coverage (fresh + reopened DB, plan uses the index)
and an Insights regression test proving tool/skill output is identical with
and without the index present.

Fixes #67341
