Open a bot's own files from a workspace conversation

A workspace run saves to the bot's own folder unless it picks the
workspace's, but a file chip in a workspace conversation only looked in
the workspace's folder, so those refs rendered as dead text. The chip
now sends both ids and the single-file lookup also searches the bot's
own folder for a user who reaches that bot.

 ### Bot files and folders
 
 - Files live on the data volume, not on computers: `DATA_DIR/bots/<id>` and `DATA_DIR/workspaces/<id>`. Catalog `bot_files`, bytes in private `media` (`bot-file`) written by `recordBotFile`. Reach via `grabStorageScopes`; paths via `resolveBotPath` (no absolute, `..`, NUL, symlink escape); quota checked by `assertStorageRoom`.
-- Tools in `src/harness/tools/storage/` (every run). `attach` puts a file on the reply. `grabConversationFiles` must list the **whole** folder tree, or nested `[file:ID]` refs render dead.
+- Tools in `src/harness/tools/storage/` (every run). `attach` puts a file on the reply. `grabConversationFiles` must list the **whole** folder tree, or nested `[file:ID]` refs render dead. A workspace run saves to the bot's own folder unless it picks the workspace's, so a chip in a workspace conversation looks up both (`api/admin/bots/files?file_id=` with `bot_id` and `workspace_id`).
 - `import_file` copies from a computer through the sandbox's streaming `GET /v1/file/download`, **never through its shell** (`/v1/shell/exec` caps output at ~30K chars and silently truncated imports). Size read first, `change_policy=abort`, length checked.
 - Ingestion: chunks + embeddings into `bot_file_chunks` / `bot_file_vectors` (vec0), worked by `src/file-ingest/`; without an embedding model search falls back to words and says so. sqlite-vec limits: metadata columns are NOT NULL; side-car columns can't be filtered with `MATCH` (filter in code). **Never pass `--vector` to `bunx bun-sqlite schema` in `entrypoint.sh`** (wipes vectors on boot). Changing `AppData.EmbeddingDimensions` needs a manual `--vector` run and a re-ingest.
 - **Foreign keys are off per connection** unless `enableForeignKeys` ran (only `src/server.ts` does). Scripts never fire `ON DELETE CASCADE`, so **any helper that deletes a parent row must delete its children explicitly** (as `deleteBotFile`, `purgeStorage`, `deleteSkill` do). A leftover child fails the next `bun run db:schema` with a foreign key violation.
