python/sandbox/v0.1.11

## What's New

### Features

- Added `resourceRequests` to sandbox creation so Kubernetes-backed sandboxes can set resource requests separately from limits. Omitting the field preserves the existing behavior where requests match limits.
- Added line-based file reads through `GET /files/download` with `offset` and `limit` query parameters. The Python sync and async SDK surfaces were regenerated and wired through to support reading large text files by line range.
- Added directory listing support through the new execd directory API. The SDK now exposes depth-controlled traversal and file entry types, while symlinks are reported as symlinks and are not recursively traversed. https://github.com/opensandbox-group/OpenSandbox/pull/1001
- Added detailed replace-content feedback without breaking existing callers. Existing replace methods keep their original behavior, while detailed methods opt in to per-file `replacedCount` results so callers can detect no-match and multi-match replacements. https://github.com/opensandbox-group/OpenSandbox/pull/991
- Added Credential Vault support to the Python SDK path and aligned it with the multi-language SDK coverage for credential injection flows. https://github.com/opensandbox-group/OpenSandbox/pull/1009 https://github.com/opensandbox-group/OpenSandbox/pull/1023

### Bug Fixes

- Fixed resourceRequests-related Python SDK tests and generated model handling.
- Fixed replace-content detailed response handling by using the generated verbose parameter and preserving the non-verbose compatibility path.
- Synced generated Python SDK code with the latest lifecycle and execd specs.

### Misc

- Bumped the Python Sandbox SDK fallback version and default User-Agent to `0.1.11`.
