Dev and engine build versions collapsed before telemetry
Internal build versions get trimmed before metrics are sent, so daily builds report one value.

What
A version field matching a dev or engine build pattern has its .tNNN.shaXXXX suffix stripped before the metric is emitted, leaving x.y.z-dev.YYYYMMDD.
Details
- Runs alongside the existing metric normalisations that collapse
mcp__* tool names to mcp and unknown model names to other. - The effect is lower per-build cardinality, since every dev or engine build of the same day now reports one value rather than one per commit.
- Not gated; applies to all builds that emit metrics.
Evidence
(?:dev|engine)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
