Add 0.7 configuration contract and adapter

[Gudge (MGudgin)]

This PR adds the exact published 0.7.0-alpha contract and its adapter to the current wxc_common wire model.

Details

• Adds recursively closed 0.7 request types for annotations and the stable Seatbelt surface.
• Preserves AppContainer and macOS Sandbox compatibility aliases while enforcing string-only enum representations in both published contracts.
• Adds exhaustive adapter mappings, version-boundary coverage, fixtures, and current-wire equivalence tests.

Tests

• cargo fmt --all -- --check
• cargo check -p mxc_config_contract -p wxc_common
• cargo clippy -p mxc_config_contract --all-targets -- -D warnings
• cargo clippy -p wxc_common --all-targets -- -D warnings
• cargo test -p mxc_config_contract --no-fail-fast (175 tests passed)
• cargo test -p wxc_common (628 tests passed)

• The newly public annotation fields also lack rustdoc, unlike the rest of Request. Document that these fields carry the optional schema reference and ignored annotation value so consumers of the published contract understand their purpose.

    #[serde(rename = "$schema", default)]
    pub schema: OptionalField<String>,
    #[serde(rename = "_comment", default)]
    pub comment: OptionalField<serde_json::Value>,

src/core/mxc_config_contract/tests/v0_7_0_alpha/fixtures/invalid/experimental_seatbelt_moved.json:8

• This fixture is identical to the generic experimental.json case and never contains the moved Seatbelt field named by the fixture. As a result, it does not verify that the former experimental.seatbelt shape is rejected; use a seatbelt payload here so this regression case exercises the intended boundary.

  "experimental": {
    "seatbelt": {}
  }

• Remove the duplicate period in this public API documentation.
