feat(universalisos): PikeOS-style Phase B/C device drivers + Phase D microkernel
Phase B (Core Device Support) — all drivers verified in QEMU:
- Network: virtio-net cleanup, RTL8139, E1000, clause-22 MDIO PHY management,
CAN bus, industrial protocols (Modbus/Profibus/EtherCAT), controller probe+dispatch
- Block storage: RAM disk backend (write->read->verify PASSED), virtio-blk transport,
backend dispatch, real MBR+GPT partition parsers, SD/eMMC command framework
- GPIO: PL061 (verified), I2C: DesignWare (verified), SPI: PL022 (verified)
Phase C (Advanced Features):
- PCI: FULL PikeOS ARMv7 replica — transport-agnostic uos_pci_ops, config-address
encoding, BAR sizing, capability walk, enumeration+bridge recursion, MSI/MSI-X
- USB: PikeOS-style layered stack — usb.h contract, usb_core.cpp (enumeration
state machine), usb_ehci.cpp (EHCI transport)
- Display: FULL 1:1 PikeOS fbcon replica + copied font_8x16
Build foundation fixes:
- Freestanding aeabi_runtime.cpp (__aeabi_uidiv/__aeabi_uldivmod)
- PikeOS-style flat 4GB MMU section map + proper enable (unblocked device MMIO)
- guest.h MAX_GUEST_IMAGE_SIZE 256MB->16MB (BSS was 259MB)
- C/C++ linkage fixes, duplicate-virtio_net_init, MMIO access-size handling
Phase D (PikeOS ARMv7 Microkernel Port):
- D-1: Per-VM address spaces — cloned pgdirs, ASID-tagged TLB, 4K page walker,
isolation PASSED (two guests, same VA->different PAs), guest fault recovery
- D-2: IRQ dispatch backbone — 1024-slot dispatch table, real GICv2 hardware
(GICD_CTLR/GICC_CTLR/GICC_PMR/GICC_IAR/GICC_EOIR), arm_irq_handler wired
- D-3: Time subsystem — CNTVCT ns-since-boot, CNTP periodic ticker via D-2
- D-4: KDEV framework — linker-section driver registration, uos_kdev_init_all,
name lookup
- D-5: VFP/NEON — lazy enable (undef trap->CPACR+FPEXC.EN), FPEXC=0x40000000
- D-6: SMP — per-CPU state, MPIDR, IPI/SGI framework (reschedule+TLB flush)
All uos_ naming (PikeOS p4_ convention adapted). Compiles -Werror freestanding C++17.

feat(universalisos): Add comprehensive agent system and context monitoring
## Agent System
- **Plan Maintainer Agent**: Manages session context and verifies todo lists
- **Aurelio Agent**: Imports Claude Code sessions and syncs to backend
## Universalisos Kernel Run Skill
- **Build & Launch**: Automated kernel build and QEMU execution
- **Driver Script**: Test automation with output validation
- **Fixed Issues**: Section directive errors, exception handlers, stack symbols
## Context Monitoring System
- **Measurement**: Real-time token counting and usage tracking
- **Continuous Monitoring**: Background compaction to prevent data loss
- **Automatic Compaction**: Preserves important context to memory
- **Alert System**: Desktop notifications for threshold events
- **Historical Tracking**: Usage trends and optimization recommendations
## Kernel Enhancements
- **Fixed boot.S**: Corrected section directives and stack symbol naming
- **Exception Handlers**: Added C stubs for ARM exception handling
- **RISC-V Support**: Added boot and exception handling for RISC-V
- **Core Components**: IPC, scheduler, heap manager, safety framework
## Integration
- **Aurelio Backend**: PortugalFuturista MCP synchronization
- **Memory System**: Context preservation before compaction
- **Automated Testing**: Driver scripts for all components
