Cargo's bare `"0.19.1"` is a caret range; its exact operator is a single `=`. The shared EXACT regex only knew pip's `==`, so the one form that is actually an exact pin in Cargo was reported as "not exact-pinned" against itself (platformer/proto-bevy, 2026-09-06). Strip the operator in the Rust parser; the constraint string keeps it so the report shows what is written. Co-Authored-By: Claude Code <noreply@anthropic.com>

"""`Cargo.toml` -> crates.io dependencies.
|
|
|
|
A dependency is either a bare string (`serde = "1.0.229"`) or a table with a
|
|
`version` key; path and git dependencies have no registry version and are
|
|
skipped. Cargo's bare `"1.0"` is a caret range, so only a full three-part
|
|
version counts as pinned — `"1.0"` is reported unpinned, which is correct.
|
|
Cargo's own exact operator is a single `=` (`"=1.0.229"`), which the shared
|
|
EXACT regex does not know (it spells pip's `==`), so it is stripped here.
