Grep returns resolved target paths for symlinked directories

[remixz]

Description

When grep searches a symlinked directory, its output contains the real target path instead of the requested symlink path.

This breaks subsequent tool calls when external_directory permissions allow the symlink path but not the underlying path. A read using the filename returned by grep is denied even though the original search was allowed.

Steps to reproduce

1. Create a file and symlinked directory:

mkdir -p /tmp/repro/real
printf 'CREATE TABLE business (id INTEGER);\n' > /tmp/repro/real/schema.sql
ln -s /tmp/repro/real /tmp/repro/db_schema

2. Run grep with:

{
  "path": "/tmp/repro/db_schema",
  "include": "schema.sql",
  "pattern": "CREATE TABLE .*business"
}

3. Observe that grep returns:

/tmp/repro/real/schema.sql

Expected:

/tmp/repro/db_schema/schema.sql
