fix(config): isolate plugin list reads from a broken JSONC layer

Plugin listing still called readConfigFile per layer, so one unparseable
project file made GET /api/config/plugins and VS Code listPluginEntries
fail. Reuse readConfigLayer isolation and pin comment-only empty parse
in the VS Code suite.

- `parseMdFile(filePath)`, `writeMdFile(filePath, frontmatter, body)`: Markdown file operations with YAML frontmatter.
- `getConfigPaths(workingDirectory)`, `readConfigLayers(workingDirectory)`, `readConfig(workingDirectory)`: Config file operations with layer merging (user, project, custom). `readConfigLayers` isolates `INVALID_JSONC` per layer: a broken file is omitted from the merge (`{}` for that layer only), recorded on `layerErrors`, and does not block valid sibling layers. Writes still refuse to overwrite the broken file.
- `readConfigFile(filePath)`: Reads one config file. Missing, whitespace-only, and comment-only files (no JSON value) return `{}`. A `jsonc-parser` error that produces a partial or non-object tree throws `INVALID_JSONC` — partial parse trees must never be treated as authoritative (avoids rewriting a `$schema`-only stub over a full config).
- `readConfigLayer(filePath)`: Same parse as `readConfigFile`, but isolates `INVALID_JSONC` to `{ config: {}, error }` so plugin/MCP/agent readers can skip one broken layer without aborting valid siblings. Writes still refuse to overwrite the broken file.
- `writeConfig(config, filePath)`: Writes config with automatic backup. Refuses to overwrite an existing non-empty file that fails the same JSONC parse check.
- `getJsonEntrySource(layers, sectionKey, entryName)`: Resolves which config layer provides an entry. A failed custom or user layer throws `INVALID_JSONC` instead of treating that file as empty. A failed project layer is skipped so a valid user/custom entry can still be found.
- `getJsonWriteTarget(layers, preferredScope)`: Determines write target for config updates. Throws `INVALID_JSONC` when the chosen target file is the unparseable layer.
