Disable default hotplug memory allocation

[sjmiller609]

Summary

• stop filling in 3GB of hotplug RAM when Hypeman clients omit hotplug_size, leaving it zero unless explicitly requested
• ensure API response reflects zero hotplug memory and adjust instance manager defaults/documentation accordingly

Testing

• Not run (not requested)

---

Note

Medium Risk
Changes instance-creation resource defaults (memory allocation behavior) and API contract around hotplug_size, which could affect existing clients’ sizing expectations but is localized and covered by a new test.

Overview
Stops implicitly allocating 3GB of hotplug memory when hotplug_size is omitted during instance creation; hotplug memory now remains 0 unless explicitly requested, and responses reflect this.

Updates OpenAPI/docs and domain comments to match the new semantics, adds a regression test asserting the omitted-hotplug_size path passes 0, and tweaks CI/tooling: pins Go to 1.25.4, ensures Linux CI installs e2fsprogs/iptables, and forces a stable PATH under sudo for make test-linux.
