Add config JSON schema generation from Zod and expose via resource call

[Copilot]

Generate JSON Schema from the Zod config schemas in src/types/config.ts and serve it via a backend /schema/config resource endpoint. Includes CI validation, a pre-commit hook to keep the schema in sync, and an ESLint guard to ensure config types remain self-contained.

Schema generation

• Export GitHubDataSourceOptionsSchema and GitHubSecureJsonDataSchema from src/types/config.ts
• All Zod schema fields include .describe() calls so that human-readable descriptions (plan types, auth types, URLs, app IDs, tokens, keys) are propagated into the generated JSON Schema
• Add scripts/generate-config-schema.ts — uses Zod v4's built-in z.toJSONSchema() to produce JSON Schema for both jsonData and secureJsonData
• Outputs to pkg/schema/config.json (Go embed)
• New npm script: yarn generate:config-schema

Backend resource endpoint

• pkg/schema/config.go — embeds the generated JSON schema via //go:embed
• pkg/plugin/instance.go — CallResource intercepts schema/config path and returns the embedded schema; all other paths delegate to SchemaDatasource as before

if req.Path == "schema/config" {
    return sender.Send(&backend.CallResourceResponse{
        Status:  http.StatusOK,
        Headers: map[string][]string{"Content-Type": {"application/json"}},
        Body:    schema.ConfigSchemaJSON,
    })
}

Local import guard (ESLint)

• Added an ESLint no-restricted-imports rule in eslint.config.mjs scoped to src/types/config.ts that blocks any relative imports ('./*', '../*'), ensuring all config types remain self-contained in a single file
• The CI workflow runs yarn lint against src/types/config.ts to enforce this guard

CI workflow

• .github/workflows/check-config-schema.yml — triggers on changes to src/types/config.ts or the generation script, lints config types for import violations, regenerates the schema, and fails if the committed version is stale

Pre-commit hook

• scripts/pre-commit — auto-regenerates and stages the schema file when src/types/config.ts is modified
• Install: cp scripts/pre-commit .git/hooks/pre-commit && chmod +x .git/hooks/pre-commit

@copilot remove unnecessary/irrelevant golden file changes.

Use schema/config as path for schema file. Use the same for resource call path.

Is there any guard we can put in such a way that all the config types lives in a same file and no imports from local files? This is to make sure no other changes affect the schema.

Done in a141114:

1. Golden files reverted — all testdata golden file changes removed from the PR.
2. Path updated to schema/config — schema files now at src/schema/config.json and pkg/configschema/config.json, resource endpoint at /schema/config.
3. Local import guard added — the generation script (scripts/generate-config-schema.ts) scans config.ts for relative imports (e.g., from './...' or from '../...') and fails with a clear error if any are found. The CI workflow also has a separate guard step that catches this early. This ensures all config types must be self-contained in src/types/config.ts with no local file dependencies.

@copilot - why still there are duplicate json files? We don't want json schema files inside src folder. Instead we want inside pkg folder with proper naming convention.

Also wondering if there is any eslint rule we can put as a import guardrail instead of custom script?

Also wonder...

Done in d22ba25:

1. Single schema location — removed src/schema/config.json. Schema is now generated only to pkg/configschema/config.json (embedded by Go). Generation script, CI workflow, and pre-commit hook all updated accordingly.

2. ESLint no-restricted-imports rule — added to eslint.config.mjs scoped to src/types/config.ts. Any relative import (e.g. from './...' or from '../...') will trigger an ESLint error:

   error  './other' import is restricted from being used by a pattern. 
   src/types/config.ts must be self-contained with no local imports to ensure reliable schema generation.
   

   The CI workflow now runs yarn lint --no-cache -- src/types/config.ts as the import guard step instead of a custom grep script.

@copilot - Still I see irrelevant golden jsonc files.

• rename the configschema package to schema
• rename the configschema.go to config.go inside pkg\schema folder

Done in 731551b:

1. Golden files reverted — all testdata .golden.jsonc file changes removed from the PR.
2. Package renamed — pkg/configschema/ → pkg/schema/, configschema.go → config.go. All references updated in instance.go, generation script, CI workflow, and pre-commit hook.

@copilot - Add description for each field to config typescript schema so that they will be generated in the JSON schema.

@copilot - Add description for each field to config typescript schema so that they will be generated in the JSON schema.

Done in bb1726d. Added .describe() to every field in the Zod config schemas — plan types, auth types, URLs, app IDs, tokens, and private keys all now have descriptions that flow through to the generated JSON schema.
