fix(wire): tolerate coherence finding codes this build has never heard of

[rennehan]

Closes the CLI half of the open-finding-code contract.

The break

Finding.code is an open set server-side — codes are added additively as new coherence rules ship. The vendored spec closed it into a generated enum:

pub enum Code { UnsatisfiedInput, DanglingWire, TypeMismatch }

No catch-all, no #[serde(other)]. The first validate response carrying a code this build has not heard of fails to deserialize entirely — not the one unfamiliar finding, the whole response. An installed CLI that is merely out of date becomes one that cannot read a validate response at all, and every additive server-side rule becomes a coordinated release.

The fix

The server now publishes code as a plain string with the known values in its description, so regenerating drops the enum altogether.

That is stronger than adding an Unknown arm: there is no closed type left to fall out of, and the unrecognized code survives as the string the server sent rather than collapsing into a variant with no name in it. A user told orphan_node can search for orphan_node; a user told Unknown cannot.

Consequences in src/:

• partition::key loses the serde_json::to_value round-trip it used to recover the enum's wire spelling — f.code is already that string.
• validate::code_str's three-arm match is deleted; human and JSON output print whatever the server said.

severity deliberately stays closed. It is a two-valued verdict the CLI branches on to pick an exit code, so a third value is a real breaking change that should fail loud rather than fall through to "not an error". Pinned by a test.

Regeneration scope

openapi.json was re-vendored and wire/ regenerated from it, so this also picks up the project and branch lifecycle routes and the decisions read surface that landed on the server since the last vendor. No src/ change was needed for those — they are additive.

Tests

Three new tests in src/cmd/validate.rs: an unknown code deserializes, an unknown code is rendered verbatim, and an unknown severity is still rejected. cargo test green (485 tests), cargo clippy -D warnings clean, cargo fmt --check clean.
