Replace otadump with pinned AOSP Android 17 extractor

[akhilnarang]

Summary

• replace the Rust extractor and custom delta implementation with a minimal Python API around AOSP ota_extractor
• pin the official android17-release build 14524720 artifact and verify both the 32,496,582-byte runtime bundle and every extracted runtime file
• support raw payloads, stored OTA ZIP payloads, selected partitions, incremental source images, and serial extraction on Linux x86_64
• add deterministic artifact-subset generation, a locked concurrent cache installer, focused offline tests, and minimal AGENTS.md test rules

Validation

• python -m unittest discover -s tests -v: 8 passed
• python tests/artifact_smoke.py: passed against a cold verified download
• python -m build: sdist and wheel built successfully
• deterministic artifact rebuild reproduced 96c5df0...
• readelf confirmed x86_64 and $ORIGIN/../lib64 RUNPATH; ldd found no missing libraries
• Pong incremental OTA subset reconstructed and passed AOSP target hash verification for boot, dtbo, recovery, vbmeta, vbmeta_system, vbmeta_vendor, and vendor_boot
• independent final review found no issues

This is based directly on mainline; it does not modify or depend on PR #1.

Superseded by #2, which now preserves the Rust full-OTA extractor and adds the reviewed, hardened incremental LineageOS backend. PR #2 is green across Python, wheel, and all release target checks.
