feat: use top-level key for repo type instead of type field

Replace the flat `remotes:` map (with `type: "remote"/"virtual"/"local"`) with separate top-level sections — `remote:`, `virtual:`, `local:` — so the repo type is declared structurally and the `type:` field is no longer needed. Config loader normalises the new format to the existing internal representation (injecting `type` into each remote dict), so all handler code is unchanged. Adds a TestYamlTypeKeys suite covering all three type keys, mixed files, and field preservation. Includes README migration guide for splitting a single remotes file into per-type-and-package conf.d files.

 ## Migration
 ### Splitting a single remotes file into per-type files
 The old format used a single `remotes:` map with an explicit `type:` field on each entry. The new format uses top-level type keys (`remote:`, `virtual:`, `local:`) and supports splitting across multiple files via `config_dir`.
 **Before** (`remotes.yaml`):
 ```yaml
 remotes:
  dockerhub:
    base_url: "https://registry-1.docker.io"
    type: "remote"
    package: "docker"
    cache:
      immutable_ttl: 0
      mutable_ttl: 300
  hashicorp-helm:
    base_url: "https://helm.releases.hashicorp.com"
    type: "remote"
    package: "helm"
    immutable_patterns:
      - "\\.tgz$"
    cache:
      immutable_ttl: 0
      mutable_ttl: 3600
  helm-all:
    type: "virtual"
    package: "helm"
    members:
      - hashicorp-helm
  local-files:
    type: "local"
    package: "generic"
 ```
 **After** — one file per type + package type, with a main config pointing at the directory:
 `config.yaml`:
 ```yaml
 config_dir: conf.d
 ```
 `conf.d/remote-docker.yaml`:
 ```yaml
 remote:
  dockerhub:
    base_url: "https://registry-1.docker.io"
    package: "docker"
    cache:
      immutable_ttl: 0
      mutable_ttl: 300
 ```
 `conf.d/remote-helm.yaml`:
 ```yaml
 remote:
  hashicorp-helm:
    base_url: "https://helm.releases.hashicorp.com"
    package: "helm"
    immutable_patterns:
      - "\\.tgz$"
    cache:
      immutable_ttl: 0
      mutable_ttl: 3600
 ```
 `conf.d/virtual-helm.yaml`:
 ```yaml
 virtual:
  helm-all:
    package: "helm"
    members:
      - hashicorp-helm
 ```
 `conf.d/local-generic.yaml`:
 ```yaml
 local:
  local-files:
    package: "generic"
 ```
 Set `CONFIG_PATH` to the main file:
 ```
 CONFIG_PATH=/etc/artifactapi/config.yaml
 ```
 Files in `conf.d/` are merged alphabetically; later files win on conflicts within the same remote name.
