feat(workspaces): migrate to Deno workspaces and improve validation

This commit introduces two major improvements to the monorepo structure and a key dependency:

1.  **Migration to Deno Workspaces:**
    The project has been migrated to use Deno's native workspace functionality. This simplifies local package management and dependency resolution.
    - An import map has been added to the root `deno.json` for all internal packages (e.g., `@mcpc/core`).
    - Package `deno.json` files now use `workspace:^` to reference other packages within the monorepo, replacing the previous `jsr:` specifiers.
    - Package versions have been bumped across the repository to reflect these structural changes.

2.  **Refactor Validation in `plugin-code-execution`:**
    The validation logic for tool arguments in the `plugin-code-execution` package has been refactored.
    - Switched from `json-schema-to-zod` and `zod` to using `ajv` with `ajv-errors`.
    - This removes the intermediate step of converting JSON schema to a Zod schema, simplifying the validation process and reducing dependencies.
    - Error messages are now more user-friendly, directly using the output from `ajv-errors`.
