feat(selfmod): keep self-modification private

[prha]

Summary

Keep @eve/self-modification as a private workspace package rather than shipping it through eve. It no longer has publication configuration or a changeset allowlist entry, while retaining the AI Gateway model-search tool for the internal extension.

Validation

Focused self-modification unit coverage, package type checking, and the invariant guard passed.

Checklist

• This change was requested or approved by a maintainer
• I ran the relevant checks from CONTRIBUTING.md
• I added tests and documentation where relevant
• I added a changeset if this touches the published eve package
• DCO sign-off passes for every commit (git commit --signoff)

Implementation — 3 files · +110 / -4

Keeps the extension private, removes its publishing path, and adds its internal model-catalog lookup.

Tests — 1 file · +85 / -0

Covers catalog parsing, eligibility filtering, and the model lookup tool.

Package Drill-Down

Package Details

• Package: eve@0.49.1
• Package directory: packages/eve
• Tarball: 8.65 MB (eve-0.49.1.tgz)
• Unpacked payload: 32.61 MB across 3839 published files
• Installed footprint: 77.77 MB across 7685 installed files
• Installed root package: 31.14 MB
• Installed dependencies: 46.63 MB
• Installed package instances: 35
• Distinct installed package names: 34
• Installed dependency edges: 53
• Installed optional peer edges: 47
• Runtime dependencies: 2
• Peer dependencies: 5 (4 optional)

Installed footprint is measured from an isolated temporary npm install of the packed tarball.
Graph metrics read only package.json files in package directories directly beneath a node_modules boundary, including nested boundaries. Each directory is one package instance; distinct names come from those manifests. Dependency edges count each unique name in dependencies or optionalDependencies per instance; optional peer edges count peerDependencies marked optional.

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: 2.96 s -> 2.84 s (-121.7 ms) vs prha/built-in-extension-mount (ef103a9).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.
