fix(build): adapt to Vite 8/rolldown chunking behavior

[Copilot]

Vite 8 (rolldown) extracts shared code between multiple entry points into a root-level chunk. With both tools/lib and tools/cli as entries sharing lib.ts, rolldown placed the actual code in dist/lib.mjs (root), making dist/tools/lib.mjs a thin re-export. This broke the dynamic imports in lib.ts:

// dist/lib.mjs (root) resolved agents relative to dist/, not dist/tools/
import(`./${buildAgent}/agent.mjs`)  // → dist/github/agent.mjs ❌
                                      // expected dist/tools/github/agent.mjs

Changes

• Split build:tools into two sequential builds

  • build:tools:lib — tools/lib + tool runners only; single-purpose entries prevent rolldown from extracting a shared chunk, so dist/tools/lib.mjs is the actual code again
  • build:tools:cli — tools/cli as a standalone single-entry bundle with lib.ts inlined

• New src/tools/vite.config.cli.mts for the CLI-only build

• dist/azure/manifest.config.cjs — add rolldown-runtime.mjs to packaged files; Vite 8/rolldown generates this new file for CJS→ESM conversion (required by semver)

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• vite.dev
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
