- Add mount.asr parser in auto_mount_volumes: reads MOUNT.ASR from boot
volume root, parses 'mnt {device}<src> <target>' lines, expands {device}
to the boot volume's /disk/volN path, creates symlinks for each entry
- Remove old asr.mnt persistent mount logic from auto_mount_volumes
- Remove persistent mount write ([p] flag) from MOUNT shell command
- Remove hardcoded /boot mount for boot volumes (now driven by mount.asr)
- Add iso/mount.asr with default /boot and /sys symlinks
- Update doc/vfs.md with mount.asr documentation
- 5-phase VFS architecture overhaul (path resolution, dir cache, watch/notify,
symlinks, async API)
- Add character/block device node layer with /dev/null and /dev/zero built-ins
- RegisterDevice() API for custom device nodes with read/write/size callbacks
- Merge TOpenMode + TWriteMode into single TOpenMode enum
(omRead, omWrite, omCreate, omReadWrite, omStream)
- Add stream write support: WriteFile/WriteFileAsync now accept omStream handles
with auto-advancing offset for both device and volume FDs
- Add PPWriteOffsetHook type and writeOffsetCallback field to TFilesystem
- Add PPReadOffsetHook-based streaming reads for FAT32 and ISO9660
- Update all callers (notepad, edit, inio, wasm runner, filepicker, filedispatch,
vterminal, stdio) to new 2-param OpenFile API
- 77 unit tests (0 failures) covering path ops, dir cache, symlinks, watch,
device nodes, and stream read/write
- Add doc/vfs.md — comprehensive public VFS API documentation
