feat: wire up memory_mb and cpus in builds API

[hiroTamada]

Summary

• Parses memory_mb and cpus fields from the multipart form data in the /builds endpoint
• Added memory_mb and cpus to the /builds endpoint's OpenAPI schema so they appear in generated SDKs
• Fixed: negative values now treated as "use default" in ApplyDefaults()
• Added maximum limits: 8 vCPUs and 16GB memory - returns 400 if exceeded

Test plan

• Verify build with custom memory_mb value uses the specified memory
• Verify build with custom cpus value uses the specified CPU count
• Verify builds without these fields continue to use defaults
• Verify negative values use defaults (not rejected or passed through)
• Verify cpus > 8 returns 400 error
• Verify memory_mb > 16384 returns 400 error

Note

Medium Risk
Changes how build resource limits are accepted and validated, which can affect builder VM sizing and build scheduling. Risk is mitigated by added server-side bounds checks and defaulting behavior.

Overview
Wires memory_mb and cpus through the POST /builds multipart handler so callers can request builder VM memory/CPU alongside timeout_seconds, and rejects out-of-range values with a 400 via new BuildPolicy.Validate() limits.

Updates the OpenAPI schema (and regenerated swaggerSpec/SDK types) to expose memory_mb and cpus, and tweaks BuildPolicy.ApplyDefaults() to treat non-positive values as “use defaults”.
