Subject: dev, kernel: Milestone towards 0.0.2, see details.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Details:

	- Added support for 512 process teams (kTeams array).
	- New SwitchTeam() API in UserProcessScheduler.
	- Kernel main loop rotates active team every 200ms.
	- Renamed syscall tables for clarity (kSyscalls → kSysCalls, etc.).
	- Replaced kKernelMaxSystemCalls with kMaxDispatchCallCount.
	- Updated call sites to match new naming.
	- Bumped format version to 0x0101.
	- Added reserved fields to HEFS_BOOT_NODE for future use.
	- Changed inode indexing logic to operate on (start, size) pairs.
