Feels like there's a lot of duplication in the cpu files, will have to comb through and trim it down.
Add a new port for Microchip ATtiny (ATtiny85, ATtiny84) with HAL, board definitions (Digispark, Adafruit Trinket, Adafruit Gemma), and blinky examples including an interrupt handler example. Also fix the AVR startup logic for both avr25 and avr5: - Place vector table in microzig_flash_start section so it lands at address 0x0 where the hardware expects it - Emit full vector table with entries for all interrupt vectors, not just the reset vector - Add InterruptOptions so users can specify interrupt handlers via microzig_options, which get wired into the vector table - Update calling convention names for zig 0.15.2 compatibility (.avr_signal/.avr_interrupt/.auto, .@"fn") Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
