feat: add procfs directory listing for ls /proc#168
Merged
Conversation
Add ProcfsDirectory fd type and handle_procfs_getdents64() handler, following the same pattern as DevfsDirectory. This enables `ls /proc` to list all procfs entries including dynamic PID directories. The handler supports three directory contexts: - /proc: lists static entries (uptime, meminfo, stat, etc.) plus dynamic PID directories from the process manager - /proc/trace: lists tracing sub-entries - /proc/[pid]: lists per-process files (status) Also adds ProcfsDirectory match arms in all exhaustive FdKind matches across both x86_64 and ARM64 syscall handlers.
