⚠ rag-rat-core breaking changes

--- failure enum_no_repr_variant_discriminant_changed: enum variant had its discriminant change value ---

Description:
The enum's variant had its discriminant value change. This breaks downstream code that used its value via a numeric cast like `as isize`.
        ref: https://doc.rust-lang.org/reference/items/enumerations.html#assigning-discriminant-values
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/enum_no_repr_variant_discriminant_changed.ron

Failed in:
  variant ParserKind::Markdown 6 -> 7 in /tmp/.tmp0WpVJq/rag-rat/crates/rag-rat-core/src/index/parser.rs:53
  variant Language::Markdown 5 -> 6 in /tmp/.tmp0WpVJq/rag-rat/crates/rag-rat-core/src/language.rs:16

--- failure enum_variant_added: enum variant added on exhaustive enum ---

Description:
A publicly-visible enum without #[non_exhaustive] has a new variant.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#enum-variant-new
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/enum_variant_added.ron

Failed in:
  variant ParserKind:Python in /tmp/.tmp0WpVJq/rag-rat/crates/rag-rat-core/src/index/parser.rs:52
  variant OracleTool:ScipPython in /tmp/.tmp0WpVJq/rag-rat/crates/rag-rat-core/src/index/oracle/mod.rs:573
  variant Language:Python in /tmp/.tmp0WpVJq/rag-rat/crates/rag-rat-core/src/language.rs:15

--- warning partial_ord_enum_variants_reordered: enum variants reordered in #[derive(PartialOrd)] enum ---

Description:
A public enum that derives PartialOrd had its variants reordered. #[derive(PartialOrd)] uses the enum variant order to set the enum's ordering behavior, so this change may break downstream code that relies on the previous order.
        ref: https://doc.rust-lang.org/std/cmp/trait.PartialOrd.html#derivable
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/partial_ord_enum_variants_reordered.ron

Failed in:
  Language::Markdown moved from position 6 to 7, in /tmp/.tmp0WpVJq/rag-rat/crates/rag-rat-core/src/language.rs:16

SCIP oracle — resolution report

Heuristic→compiler edge resolution per corpus. Δ compares resolved-after to the main baseline (only when the corpus profile + tool version match).

corpus	tool	edges	resolved (heuristic → compiler)	precision	recall	monikers	Δ vs main
c-cjson	scip-clang	3941	69.6% → 86.5%	89.0%	80.8%	911	+0.0pp
py-requests	scip-python	1060	32.5% → 71.7%	89.9%	86.8%	292	+0.0pp
rust-semver	rust-analyzer	1056	39.0% → 88.6%	79.6%	100.0%	78	+0.0pp

_{resolved = Exact/Syntactic + compiler upgrades + resolved-external, over edge candidates with a callee range. precision/recall are the oracle eval metrics.}

Include the latest merged feature in 0.7.0 notes

This release commit is based on 8b6adfe, whose direct history since the 0.6.0 release includes feat(oracle): Markdown resolution report — job summary + fork-safe PR comment (C5) (#178), but the newly added 0.7.0 changelog starts at #177 and never mentions #178. Users reading the 0.7.0 notes will miss a shipped feature unless the release PR is regenerated or this section is updated before publishing.
