chore(release): prepare FAT 2.0.0 for macOS, Linux, and Windows

[adi0x90]

Prepare FAT 2.0.0 as the first regular release of the Rust CLI, with native downloads for macOS, Linux, and Windows and a repeatable release process.

Changes

• Synchronize all workspace crates, internal dependency requirements, runtime data, and citation metadata at 2.0.0 while retaining Rust 2024.
• Use cargo-release for version updates, git-cliff for release-note drafts, and cargo-dist for native platform archives and GitHub release automation.
• Build macOS Apple Silicon and Intel, Linux x86-64 and ARM64, and Windows x86-64 archives with matching runtime data, release notes, and dependency licenses.
• Test extracted archives on every target and test both Linux builds on Fedora 42 before publication.
• Support runtime data beside a portable executable as well as the existing bin/share installation layout.
• Add curated first-release notes, SemVer and release instructions, a README release badge, download links, and installation guidance.

Validation

• Formatting and strict workspace Clippy passed.
• All 16 data CLI tests and 9 data-resolver tests passed, including the reproduced and fixed prefix-layout regression.
• All 10 source-installer tests and verification of the 33 runtime-data files passed.
• Rehearsed minor and prerelease version updates, asset-name replacements, changelog generation, and the single product tag in a disposable repository.
• All 1,954 workspace tests passed, with no failures or ignored tests.
• All five native builds and extracted-archive smoke tests passed; both Linux archives also passed on Fedora 42.
