Add Meta Quest 3 teleoperation support

Summary

This PR adds Meta Quest 3 as an alternative input device for the GEAR-SONIC teleoperation system. Users can run the manager with Quest controllers (USB or WiFi) in addition to the existing Pico-based flow. The default remains Pico; Quest is opt-in via --reader quest.

Changes

• Quest reader (gear_sonic/utils/teleop/readers/quest_reader.py): New QuestReader that implements the same sample interface as PicoReader. Uses meta_quest_teleop to read controller poses, maps them to the existing VR 3-point pose format (L-Wrist, R-Wrist, Head), and corrects Quest coordinate axes to the robot frame (X=forward, Y=left, Z=up). Supports USB and WiFi (--quest-ip-address), calibration via right trigger, and optional ADB/synthetic modes for testing.
• Manager integration (gear_sonic/scripts/pico_manager_thread_server.py): New CLI options --reader {pico|quest} (default: pico) and --quest-ip-address. When --reader quest, the manager uses QuestReader and reads controller state (A/B/X/Y, triggers, grips, joysticks) from the Quest sample for mode switching and locomotion. Calibration uses G1 FK default pose as reference, same as the validation script.
• Validation and testing: validate_quest_raw for 3D visualization of Quest tracking (raw or G1-calibrated), and test_quest_meta_quest.py for a quick connection check. ADB test via python -m gear_sonic.utils.teleop.readers.quest_reader --test-adb.
• Dependencies: Optional dependency meta_quest_teleop added under the existing gear_sonic[teleop] extra in pyproject.toml.
• Docs: Setup guide for Quest 3 (requirements, ADB, calibration, full sim + deploy + Quest workflow) in TELEOPERATION_QUEST_SETUP.md and reader usage in gear_sonic/utils/teleop/readers/README.md.

Backward compatibility

• Pico unchanged: Default reader is pico. All Pico code paths (XRoboToolkit, body tracking, SMPL 3-point pose) are unchanged. Existing users continue to use the same commands without modification.
• Quest is additive: No breaking changes to existing APIs or CLI; Quest is selected only when --reader quest is passed.

How to use (Quest)

# USB (recommended for first use)
python gear_sonic/scripts/pico_manager_thread_server.py --manager --reader quest

# WiFi
python gear_sonic/scripts/pico_manager_thread_server.py --manager --reader quest --quest-ip-address 192.168.x.x

# With VR 3-point visualization
python gear_sonic/scripts/pico_manager_thread_server.py --manager --reader quest --vis_vr3pt

Connect the Quest, start the manager, then press right trigger to calibrate (adopt G1 default pose first). See TELEOPERATION_QUEST_SETUP.md for full setup (ADB, developer mode, install).

Tested

• Meta Quest 3 hardware (controllers, USB and WiFi)
• Ubuntu 22.04

This allows using the teleoperation system with Meta Quest 3 devices in addition to Pico, without affecting existing Pico users.
