feat(eve): deploy declarative agent collections

[OwenKephart]

Description

Makes a declared, hostless collection deployable as peer Vercel services. From the collection root, eve build infers one service for each strict agents/<name>/agent/ member and exposes it at /eve/agents/<name>/eve/v1/*.

my-agents/
├── package.json                 # { "eve": { "collection": true } }
├── .env.local                   # shared by every collection member
└── agents/
    ├── support/agent/
    └── research/agent/

For example, the following root package opts into the inferred deployment path:

{
  "name": "my-agents",
  "private": true,
  "type": "module",
  "eve": { "collection": true },
  "scripts": {
    "build": "eve build"
  },
  "dependencies": {
    "eve": "^0.x"
  }
}

The collection root owns build, link, and deploy; member commands run one selected agent and inherit the shared root environment. Child directories do not define package.json files or build scripts.

The inferred graph is deliberately the no-configuration path. If vercel.json declares services, that authored graph remains authoritative; use vercel build for heterogeneous projects with a frontend, private APIs, bindings, or other services. A framework app using withEve is also an explicit alternative: its framework build owns deployment assembly and is not required to use the strict collection layout.

Build Timing: e2e/fixtures/agent-tools-sandbox

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

• Build pipeline: 2.22 s -> 2.25 s (+32.3 ms) vs feat/agent-collection-topology (274d7e4).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.

buildAgentCollection() emits service configs whose root points to .eve/vercel-services/<serviceName> directories that it never creates on disk, causing the Vercel Services build to fail.
