fix(cli): scaffold embeddings section in config --init

[carlos-alm]

Summary

• buildInitTemplate() in src/cli/commands/config.ts never included an embeddings block, so codegraph config --init scaffolded llm, query, build, ci, and search but omitted embeddings entirely — including the provider field added in feat(search): configurable remote embedding provider for codegraph embed #1716 for the remote embedding backend.
• Adds an embeddings block (model, llmProvider, provider) mirroring DEFAULTS.embeddings, placed next to llm since the remote provider option relies on llm.baseUrl/apiKeyCommand.

Closes #1718

Test plan

• Added Config CLI commands > config --init scaffolds an embeddings section alongside llm in tests/integration/cli.test.ts, verifying the scaffolded file contains embeddings: { model: null, llmProvider: null, provider: null }
• npx vitest run tests/integration/cli.test.ts — 30/30 passed
• npx vitest run tests/unit/config.test.ts tests/unit/config-user.test.ts — 88/88 passed
• npm run lint — clean
• codegraph diff-impact --staged -T — change contained to buildInitTemplate and its 2 transitive callers

Greptile Summary

This PR fixes a gap in codegraph config --init where buildInitTemplate() produced a scaffolded config that omitted the embeddings section entirely, leaving users unaware of the remote-provider option introduced in #1716.

• Adds an embeddings: { model, llmProvider, provider } block to buildInitTemplate(), directly mirroring DEFAULTS.embeddings and placed adjacent to llm since the remote provider relies on llm.baseUrl/apiKeyCommand.
• Adds an integration test that pins CODEGRAPH_USER_CONFIG and clears XDG_CONFIG_HOME/APPDATA to avoid CI path-resolution divergence, then verifies the scaffolded file contains the expected null-initialised embeddings block.

Confidence Score: 5/5

Safe to merge — the change is a one-block addition to a template builder, with a well-isolated integration test that guards against CI path-resolution quirks.

The fix directly references DEFAULTS.embeddings so it can never diverge from the actual schema defaults. The test pins the scaffolded file path via CODEGRAPH_USER_CONFIG and explicitly clears competing env vars, making the assertion deterministic on all platforms. No existing behaviour is altered.

No files require special attention.

Important Files Changed

Filename	Overview
src/cli/commands/config.ts	Adds the missing embeddings block to buildInitTemplate(), correctly reading all three fields from DEFAULTS.embeddings and placing the block between llm and query as intended.
tests/integration/cli.test.ts	New integration test carefully isolates the file-system side-effects of --init using CODEGRAPH_USER_CONFIG, unsetting XDG_CONFIG_HOME and APPDATA to stay correct on CI runners, and asserts the exact shape of the scaffolded embeddings block.
