Add embedded device library registry with full lifecycle management, automated test integration, and pin assignment workflow. Library system: - Library registry embedded in binary via include_dir! (same as templates) - library.toml metadata format: name, version, bus type, pins, provided files - anvil add <name> extracts headers to lib/drivers/<name>/, test files to test/ - anvil remove <name> cleans up all files, config entries, and include paths - anvil lib lists installed libraries with status - anvil lib --available shows registry with student-friendly wiring summary - [libraries] section in .anvil.toml tracks installed libraries and versions - CMake auto-discovers lib/drivers/*/ for include paths at configure time TMP36 analog temperature sensor (reference implementation): - TempSensor abstract interface (readCelsius/readFahrenheit/readRaw) - Tmp36Analog: real hardware impl via Hal::analogRead with configurable Vref - Tmp36Mock: programmable values, read counting, no hardware needed - Tmp36Sim: deterministic noise via seeded LCG for repeatable system tests - test_tmp36.cpp: 21 Google Test cases covering mock, analog, sim, polymorphism - TMP36 formula: voltage_mV = raw * Vref_mV / 1024, temp_C = (mV - 500) / 10 Automated test integration: - Library test files (test_*.cpp) route to test/ during extraction - CMakeLists.txt auto-discovers test_*.cpp via GLOB, builds each as own target - anvil remove cleans up test files alongside driver headers - Zero manual CMake editing: add library, run test --clean, tests appear Pin assignment integration: - anvil add <name> --pin A0 does extract + pin assignment in one step - Without --pin, prints step-by-step wiring guidance with copy-paste commands - anvil pin --audit flags installed libraries with unassigned pins - Audit works even with zero existing pin assignments (fixed early-return bug) - LibraryMeta helpers: wiring_summary(), pin_roles(), default_mode() - Bus-aware guidance: analog pins, I2C bus registration, SPI with CS selection UX improvements: - anvil lib --available shows "Needs: 1 analog pin (e.g. A0)" not raw metadata - anvil add prints app code example, test code example, and next step - anvil pin --audit prints exact commands to resolve missing library pins - anvil remove shows test file deletion in output Files added: - libraries/tmp36/library.toml - libraries/tmp36/src/tmp36.h, tmp36_analog.h, tmp36_mock.h, tmp36_sim.h - libraries/tmp36/src/test_tmp36.cpp - src/library/mod.rs Files modified: - src/lib.rs, src/main.rs, src/commands/mod.rs - src/commands/lib.rs (add/remove/list/list_available with --pin support) - src/commands/pin.rs (audit library pin warnings, print_library_pin_warnings) - src/project/config.rs (libraries HashMap field) - templates/basic/test/CMakeLists.txt.tmpl (driver + test auto-discovery) Tests: 254 total (89 unit + 165 integration) - 12 library/mod.rs unit tests (registry, extraction, helpers) - 2 commands/lib.rs unit tests (class name derivation) - 30+ new integration tests covering library lifecycle, pin integration, audit flows, file routing, CMake discovery, config roundtrips, ASCII compliance, polymorphism contracts, and idempotent add/remove cycles
