- Windows: use FILE_FS_FULL_SIZE_INFORMATION_EX on Windows 10 1809+ (Build >= 17763) when calcType != AVAILABLE to get ActualTotalAllocationUnits/ActualAvailableAllocationUnits (ignoring per-user disk quotas). Fall back to legacy FILE_FS_FULL_SIZE_INFORMATION with CallerAvailableAllocationUnits when calcType is AVAILABLE or EX is unavailable.
- Unix-like: respect --disk-calc-type. Use f_bfree for FREE, f_bavail for AVAILABLE (Linux/BSD/SunOS). Haiku currently always uses free_blocks.
- Refactor FFDisk: remove bytesUsed and bytesAvailable; compute used = total - free in disk module.
- Disk module: update custom format (remove `size-available`, add `bytes-used` and `bytes-total`); update JSON output (remove `bytes.available`, `bytes.used`).
- Disk detection: stop computing used in common path; let each platform set bytesFree by chosen semantics.
Fixes#2651
Moves module option structs out of global config and removes dynamic allocation, using static buffers and size assertions for safer, simpler management.
Refactors module initialization and destruction to work with isolated option structs, eliminating the need for the previous modules container and related code.
Unifies module option header usage and updates detection logic to leverage statically-sized option buffers, improving encapsulation and maintainability.
Simplifies module function signatures and reduces coupling between modules and config.
Enhances future extensibility and reliability by enforcing max size constraints and removing unnecessary indirections.
