PR_26171_GAMMA_021-sqlite-active-runtime-removal-plan

[ToolboxAid]

Summary

• Adds a focused active SQLite runtime removal plan from the fresh-main inventory.
• Classifies active runtime, Local API, test, and docs references.
• Excludes historical report/PR archive references from removal.
• Defines replacement paths and owner-routed follow-up PR sequence for Messages, Game Journey metrics, shared mock DB adapter cleanup, Local API metadata removal, and final guard cleanup.

Validation

• git diff --check
• Targeted text verification that active SQLite references are classified.
• Targeted text verification that archive/reference paths are explicitly excluded.

Skipped by request:

• Playwright, because this is a docs/report-only planning PR.
• Samples, because no sample files or runtime behavior changed.
