What changed in this PR
Prepares Hyperlight’s workspace packages and release notes for v0.19.0. Tagging and publishing the GitHub release remain post-merge steps.
Changes:
- Sets the workspace version and internal dependency requirements to
0.19.0. - Synchronizes both lockfiles without changing third-party dependencies.
- Finalizes the v0.19.0 changelog section, adds an empty Prerelease section, and updates comparison links.

Bump the workspace version from 0.18.0 to 0.19.0 (and the internal hyperlight-* dependency versions with it), roll the CHANGELOG's [Prerelease] section into [v0.19.0] with a fresh empty [Prerelease] and the compare-link footer, and sync the root and rust_guests Cargo.lock files to match. Follows docs/how-to-make-releases.md; the tag is cut after this merges. Signed-off-by: danbugs <danilochiarlone@gmail.com>

#1968 removed SandboxBuilder::heap_size (and set_heap_size/get_heap_size), but the scratch_allocated_bytes_counts_written_pages test added by #2019 still called it, so main stopped compiling its tests once both landed — which is why clippy and miri fail on every PR. Drop the .heap_size(8 << 20) line; the test already sizes scratch with .scratch_size(16 << 20). Signed-off-by: danbugs <danilochiarlone@gmail.com>
