feature(emulator): bump emulator (v0.21.0), rootfs (v0.18.0), linux (6.5.13-ctsi-2-v0.21.0)

[mpolitzer]

Changes:

• header files got renamed
• defines renamed: CM_CMIO_* -> CM_HTIF_*; UARCH_HALT_FLAG -> UARCH_HALT
• SendCmioResponse got a new parameter: revertRootHash. Checkpoint is now done "automatically" from it.
• Need final versions of dependencies: emulator, rootfs and linux.

bumps:

• machine-emulator: 0.21.0
• machine-guest-tools: 0.18.0
• linux: 6.5.13-ctsi-2-v0.21.0

Pull request overview

This PR updates the rollups-node integration to newer Cartesi machine components (emulator/rootfs/linux) and adapts the Go/Lua tooling and machine abstractions to upstream API changes (renamed headers/defines, new CMIO response contract, and updated hash-collection entrypoints).

Changes:

• Bump emulator/rootfs/linux dependency pins (Dockerfile + test download helpers + packaging constraints).
• Update emulator CGo bindings and machine backend interfaces for renamed HTIF/CMIO constants and the new SendCmioResponse(revertRootHash, ...) API.
• Remove explicit checkpoint-hash writing and adjust replay/proof tooling for renamed flags and base64/hex hash formats.
