Recommended Rust Dependencies

Current Cargo.toml:

[dependencies]
serde = { version = "1", features = ["derive"] }
serde_json = "1"
serde_yaml = "0.9"
miette = { version = "7", features = ["fancy"] }
semver = { version = "1", features = ["serde"] }
indexmap = { version = "2", features = ["serde"] }

[dependencies.clap]
version = "4"
features = ["derive"]
optional = true

[dependencies.pyo3]
version = "0.23"
optional = true
features = ["extension-module", "abi3-py39"]

[features]
default = ["cli"]
cli = ["dep:clap"]
python = ["dep:pyo3"]

Dependency	Used for
serde / serde_json / serde_yaml	Canonical Object Model serialization
miette	CLI and file I/O error reporting
semver	dtcsVersion compatibility checks
indexmap	Stable-order maps and extension fields
clap	dtcs CLI (cli feature, on by default)
pyo3	Python bindings (python feature, via maturin)

Use serde as the serialization layer.

Use miette for developer-friendly CLI errors.

Use custom DTCS diagnostics (DiagnosticReport) for spec-level validation reporting.
