Recovery from a persisted vector-index dimension mismatch (after the user
changes EMBEDDING_PROVIDER) was unnecessarily hard:
1. The error pointed users at `AGENTMEMORY_DROP_STALE_INDEX=true` but
never told them which `.env` file the running process actually reads,
which matters under LaunchAgent / systemd / Docker contexts where
HOME can differ from the expected user directory.
2. Even after setting the flag, the dropStale branch only skipped
restoring the bad vectors in memory — the stale payload stayed in KV.
Removing the flag on the next boot would crash-loop the server again
because the persisted index was still bad.
Two minimal changes:
- Export the resolved data dir + env-file paths from config and surface
them in the error message, with a ready-to-paste `echo … >> $envFile`
recovery line and an explicit HOME-resolution note for service-managed
deployments.
- In the dropStale branch, persist the now-cleared index back via
indexPersistence.save() so the recovery is one-shot: the flag drops
the stale payload AND clears the on-disk KV, so the next boot is
clean even after the flag is removed.
Tests (1081) + build pass.

In `@src/index.ts`:
- Around line 416-418: The printed recovery command inserts
RESOLVED_PATHS.envFile raw into the shell snippet which breaks if the path
contains spaces or shell metacharacters; update the template in src/index.ts to
shell-quote or escape RESOLVED_PATHS.envFile before interpolation (e.g., call an
escape helper like escapeShellArg or wrap the path in single quotes while
escaping any embedded single quotes) so the printed command is safe to
copy-paste; ensure you replace the direct interpolation of
RESOLVED_PATHS.envFile in the multiline string with the escaped/quoted value.
