* fix(security): keep agent file tools out of the app state directory

The agent's read tools (read_file, grep, glob, ls) resolved model-supplied
paths against a root list whose first entry was the whole data directory.
That directory holds the session store, the auth database, the app
encryption key and the settings file, so prompt-injected content could ask
for any of them. No approval prompt stood in the way: reads are classified
read_workspace and pass the untrusted-context gate untouched, which is
correct for reading a workspace and wrong for reading the app's own state.

The agent gets data/agent_workspace/ instead, and the subprocess cwd and
HOME move with it so bash and read_file agree on where scratch files live.

The deny itself is a property of the path, not of the root it arrived
through, because three routes reach the same bytes and closing only the
first leaves the other two working:

  - the default root list
  - a workspace bound at or above the data directory, which vet_workspace
    accepted and chat_routes auto-binds from a path named in the message
  - a tool_path_extra_roots setting covering the data directory

_resolve_search_root also returned the workspace root unchecked when the
path was empty, so a bare ls enumerated the directory whatever the deny
list said. It now resolves that case through the same guards.

A containment rule rather than a filename deny list, so state files added
later are covered without anyone remembering to list them, and so a user's
own settings.json or app.db inside a real workspace is not caught.

Four directories of user content stay readable, because the application
hands their paths to the model and tells it to open them: the chat upload
manifest, downloaded mail attachments, personal docs (which covers the
runbook) and personal uploads.

* fix: enforce state deny during recursive file search

* fix: bound protected filesystem searches

* fix(security): reject inode aliases and workspace redirects

* fix(security): harden partitioned agent searches

* fix(security): report fallback worker exits promptly

* fix(security): clean up search readers and retain relative data roots
