Hannes 58cabbc97c Make repo release-ready: add sym-lib-table, CHANGELOG, expand .gitignore
- Add project-local sym-lib-table so the custom esp_sensair_stuff symbols
  resolve on a fresh clone (fp-lib-table already covered footprints)
- Add CHANGELOG.md documenting the v1.0.0 release
- Expand .gitignore: KiCad lock files, ESPHome build artifacts, Python
  cache, editor/OS noise, logs, merge artifacts
- README: list sym-lib-table and CHANGELOG.md in the repository layout

[1.0.0] - 2026-10-19

First public release of the ESP32-C3 CO₂ & environment sensor board (prototype v1).

Added

  • Hardware design (KiCad 10): schematic, 2-layer board layout, custom symbol library (esp_sensair_stuff.kicad_sym) and footprint library (esp_sensair_stuff.pretty/) for the ESP32-C3 module, Sensirion S8 and BME280.
  • Project-local library tables (fp-lib-table, sym-lib-table) so the design opens with all custom parts resolved on a fresh clone.
  • Fabrication data in gerber/: Gerber X2 plot, Excellon PTH/NPTH drills, Gerber job/stackup file, and a ready-to-upload esp-sensair.zip.
  • Bill of materials (bom/esp-sensair-bom.csv) plus the human-readable BOM in the README.
  • Documentation in docs/: schematic PDF, top/bottom layer plots, 3D render.
  • Firmware (firmware/): ESPHome configuration and secrets templates (*.example) for the ESP32-C3 (esp-idf), BME280 over I²C and Sensirion S8 over UART, with Home Assistant API (noise encryption) and OTA.
  • Licensing: CERN-OHL-S-2.0 for hardware (LICENSE), MIT for firmware, BOM and docs (LICENSE.MIT).
  • .gitignore covering KiCad local history/backups/lock files, ESPHome build artifacts, live firmware credentials, and OS/editor noise.

Known issues

See the "Known issues and lessons learned (v1 → v2)" section of the README. Highlights: power delivered through the module's USB-C 5 V path, single decoupling capacitor, no mounting holes, no populated I²C pull-ups, unannotated schematic, leaded HASL, and a + in the project name that leaks into Gerber file names.
