Markus Maiwald 2a1af03e28 feat(rumpk): Phase 8 - The Summoning (ELF Loader) - 95% Complete
## Major Features

### 1. Dynamic ELF64 Binary Loading
- Implemented ELF parser with full header validation (core/loader/elf.nim)
- Created kexec() loader supporting PT_LOAD segment mapping
- Added BSS initialization and data copying from VFS
- Assembly trampoline (rumpk_enter_userland) for userland entry

### 2. Syscall Infrastructure
- Added CMD_SYS_EXEC (0x400) for consciousness swapping
- Integrated exec command in NipBox shell
- Implemented syscall routing through command ring
- Added provenance tracking via SipHash

### 3. Test Binary & Build System
- Created hello.c test program for alien binary execution
- Automated compilation and initrd inclusion in build.sh
- Added libnexus.h header for standalone C programs

### 4. VFS Integration
- Implemented TarFS file cursor system for sequential reads
- Fixed infinite loop bug in cat command
- Added debug logging for VFS mount process

## Technical Improvements

### Memory Management
- Fixed input ring null pointer dereference
- Implemented CMD_ION_FREE syscall for packet reclamation
- Resolved memory leak in input/output pipeline
- Added FileHandle with persistent offset tracking

### ABI Stability
- Split kprint into 1-arg (Nim) and kwrite (C ABI)
- Fixed cstring conversion warnings across codebase
- Corrected RISC-V assembly (csrw sie, zero)

### Documentation
- Comprehensive Phase 8 documentation (docs/PHASE-8-ELF-LOADER.md)
- Detailed implementation notes and debugging status

## Current Status

 ELF parser, loader, and syscall infrastructure complete
 Test binary compiles and embeds in VFS
 Shell integration functional
🔧 Debugging command ring communication (syscall not reaching kernel)

## Files Changed

Core:
- core/loader.nim, core/loader/elf.nim (NEW)
- core/kernel.nim, core/ion.nim (syscall handling)
- core/fs/tar.nim (file cursor system)
- hal/arch/riscv64/switch.S (userland trampoline)

Userland:
- npl/nipbox/nipbox.nim (exec command)
- libs/membrane/libc_shim.zig (syscall implementation)
- libs/membrane/ion.zig (command ring API)

Build & Test:
- build.sh (hello.c compilation)
- rootfs/src/hello.c, rootfs/src/libnexus.h (NEW)
- apps/subject_entry.S (NEW)

## Next Steps

1. Debug SysTable and command ring communication
2. Verify ION fiber polling of chan_cmd
3. Test full ELF loading and execution flow
4. Add memory protection (future phase)
