Grasshopper hardening (8.180, 8.185 to 8.188) and the beta notice version. Closes #32, #33, #36, #40, #52.

Components, by change:

• Missing input is a warning (MissingInput): Actor, AddEvidence, ComputeFrame, CreateComponentIdentity, CreateComponentSnapshot, Origin, ReinforcementLayout.
• Item access, a failed item keeps a null slot, no data gives empty trees (8.186): Actor, AddComponentIdentity, AddComponentSnapshot, ApplyFrame, Capture, ComputeFrame, ComputePCAOrientation, ConvertGeoLocation, CreateComponentIdentity, CreateComponentSnapshot, ExtrusionProfile, FetchAllSnapshots, FetchOriginalGeometry, FetchReducedGeometry, FetchReinforcementLayout, FetchSimilarComponents, FetchSnapshot, GetDescriptor, IdentityMetadata, JSONKeys, ListIdentitySnapshots, Origin, ReinforcementLayout, SnapshotMetadata, TransformComponent.
• Early stop gives empty trees: all 49 components with empty_outputs.
• ReinforcementLayout: Spec optional (8.187). ReadFromD2P: D2P component put out, a warning when it cannot be resolved, clearer texts (ReadFromD2P: Component output is null although the pieces are read #36). CSC_Update: save, close and reopen after a source swap (8.188). ApplyFrame and DisassembleComponent frame descriptions. Element instead of piece in all Grasshopper text.
• AddEvidence: an invalid identity id or evidence text is an error.

Also: dev requirements pinned exactly and CI's pytest pinned to match; UMAP of the component map starts from PCA (d2b3901).

Checks: invoke test-release 3130 passed, 46 skipped; review GO; live checks in Rhino 8 passed (ReadFromD2P with a committed D2P component, ApplyFrame slots, nothing connected, ReinforcementLayout without Spec).

Server note: remove the version number from BETA_BANNER_TEXT and BETA_LOGIN_MESSAGE in the frontend .env, or use {version}.
