Consolidate mise configuration at repository root

[Kyle-Ye]

Summary

• move the Compute mise environment configuration from Example/ to the repository root
• remove the duplicated default mise configuration from Example/
• update the Example setup instructions and script to use the root configurations
• update the UI test workflow path filter for root-level mise changes

Why

The root and Example default configurations duplicated the same Tuist version and AttributeGraph environment. Keeping the default and Compute configurations together at the repository root provides one source of truth while still allowing commands run from Example/ to inherit the appropriate mise environment.

Impact

The recommended Example/setup.sh workflow remains unchanged for users. Both default AttributeGraph generation and --compute generation now resolve their mise configuration from the repository root.

Validation

• bash -n Example/setup.sh
• git diff --check
• verified default mode resolves Tuist 4.193.0 with AttributeGraph enabled
• verified Compute mode resolves Tuist 4.193.0 with the existing Compute environment overrides

The manual Compute instructions only mise trust ../mise.compute.toml, but mise --env compute … will typically still load the base ../mise.toml as well. If someone follows just this section, they may still hit an untrusted-config prompt for mise.toml.
