Vale v0.1.7

• Upgraded the workspace to Go 1.27.1 and refreshed all direct dependencies and CI tooling.
• Added in-process HTTP handler endpoints that remain available independently of upstream health.
• Added route-level write timeout overrides and safe unbuffered SSE streaming with cancellation propagation.
• Modernized public extension registries around generic, type-safe APIs while preserving workspace-first module wiring.
• Removed operational uses of the default logger in favor of injected loggers.
• Documented pure-Go Windows builds that do not require CGO or MSYS2.
