What
Many parts of the build, including the Glob, Grep and ExitPlanMode tool definitions, agent and skill frontmatter checks, the Bedrock, Foundry and Azure identity clients and WSL mount detection, are now declared at the top of the bundle instead of inside lazily-initialized wrappers. Tool descriptions and error text are unchanged, so the only effect is on startup evaluation order.
Evidence
search file contents with regex (ripgrep)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
