feat(toolchain): declare gate.language so a mislabelled repo keeps its spec truthful

+### Added

+- **`gate.language` in `.cladding/config.yaml` — a declared language label for the spec cross-check.** The manifest chain reads build orchestration, so a repository whose product language differs from its build host — a C++ SDK driven by Gradle, a Rust core shipped through npm — is mislabelled by construction, and the only way to green `TECH_STACK_MISMATCH` used to be rewriting `spec.yaml` to adopt the mislabel. Declaring the language keeps the spec truthful: the detector cross-checks `spec.project.language` against the declaration instead of the heuristic, and still warns when those two disagree, so the check keeps its teeth. Because nothing mechanical separates a legitimate build-host mismatch from a declaration left behind by a real port, the override records what it did: when the declaration and the manifest disagree, `clad check --json` reports which label is in force and what the manifest saw. It is deliberately an info-severity finding, so it never blocks the gate — and it does not appear in the gate's terminal output either, which renders only error and warn. It is there for whoever audits why a repository is green, not for the terminal.

 ## [0.9.4] — Live host health and reproducible verification (2026-08-10)
 
 **In one line:** cladding now proves that its host hooks actually fired, records what stopped or completed a run, pins generated CI to the current release line, and stamps every verified tree with the policy that earned it.
