Adds a nullable JSONB column `last_injected_context` to the `chats` table that stores the most recently persisted injected context parts (AGENTS.md context-file and skill message parts). The column is updated only when `persistInstructionFiles()` runs — on first workspace attach or when the agent changes — so there are no redundant writes on subsequent turns. Internal fields (`ContextFileContent`, `ContextFileOS`, `ContextFileDirectory`, `SkillDir`) are stripped at write time so the column only holds small metadata. No stripping needed on the read path. <details> <summary>Implementation notes</summary> - New migration `000456` adds nullable `last_injected_context JSONB` column. - New SQL query `UpdateChatLastInjectedContext` writes the column without touching `updated_at`. - `persistInstructionFiles()` strips internal fields from parts via `StripInternal()` before persisting. - Sentinel path (no AGENTS.md) persists skill-only parts when skills exist. - `codersdk.Chat` exposes `LastInjectedContext []ChatMessagePart` (omitempty). - `db2sdk.Chat()` passes through the already-clean data. </details>
