Split renderTemplate into two functions:
- renderTemplate() returns raw rendered string
- renderTemplateParsed<T>() returns parsed YAML object

This eliminates the redundant parse->dump->parse cycle where templates
were parsed to YAML, dumped back to string, then parsed again by the caller.

The lastUserData variable and _getLastUserData() function were never
used by any tests or production code. Removed to reduce dead code.

When building the combined config, log a warning if multiple apps define
the same router, service, or middleware name. This helps catch
misconfigurations where one app's config would silently overwrite another's.

if initialization failed, the next line would throw a confusing error.

Added ensureBackend() helper that explicitly checks and throws a clear
error message if the backend failed to initialize.

Previously cleanupTempFiles() ran on every config flush, causing
unnecessary filesystem operations. Now tracks cleanup state and only
runs once per output file, resetting when the output file changes.

Changed buildContext and getContextValue to use specific Record<string, ...>
types instead of 'any' to satisfy ESLint no-explicit-any rules.

…ad code

1. Fix double rendering issue:
   - renderTemplateParsed now returns { raw, parsed } to avoid calling
     renderTemplate twice (was rendering once to store, then again to parse)

2. Extract reusable error helper:
   - Added getErrorMessage(err) to templateParser.ts
   - Used in traefik.ts, templateParser.ts, and validators.ts
   - Eliminates duplicate 'err instanceof Error ? err.message : String(err)'

3. Remove dead code:
   - Removed lastRendered variable (never used)
   - Removed _getLastRendered() function (never called from tests)
   - Removed duplicate debug log in makeAppConfig (templateParser already logs)

Define a dedicated Context type and use safe unknown-based lookup in
getContextValue to satisfy TypeScript without resorting to 'any'.

- Add  with  and
- Use helpers across parser, validators, and manager
- Minor readability improvements

- Remove duplicate ComposeFileReference from docker.d.ts (use provider's version)
- Remove TraefikConfigYamlFormat re-export from types/index.ts (keep in backend)
- Remove duplicate FieldData type from api/types.ts
- Extract shared getClientIP utility from auth.ts and logging.ts
- Clean up config.ts comments (fix typos, improve clarity)
- Remove unnecessary re-export in templateParser.ts

- Reorganize logger.ts imports (group and move type import to top)
- Add JSDoc comments to logging functions
- Clean up verbose comments and simplify code
- Export getClientIP from middleware index
- Simplify consoleFormat data source selection

- Reorganize config.ts imports at top
- Extract VALID_BACKENDS as const array
- Add JSDoc comments to exported functions
- Convert BackendModule and BackendStatus to exported interfaces
- Add JSDoc comments to backend plugin functions

- Move detectCollisions import to top of file with other imports
- Remove redundant section headers (Flush Debouncing)
- Simplify comments on module state variables

- Remove unused xMagicProxySchema alias export
- Rewrite backends/readme.md with cleaner formatting and updated references
