Introduces a logger.ts module emitting slog-compatible JSON lines to stderr. Replaces silent catch blocks and console.error calls throughout minio.ts, pocketbase.ts, hooks.server.ts, login, books, browse, and all API routes so auth/registration failures, MinIO presign errors, and scraper proxy failures are now visible in container logs.

/**
|
|
* Structured server-side logger.
|
|
*
|
|
* Emits JSON lines to stderr so they appear in container/process logs without
|
|
* polluting stdout (which Node's HTTP layer uses for responses).
|
|
*
|
|
* Format mirrors Go's log/slog default JSON output:
|
|
* {"time":"…","level":"ERROR","msg":"…","context":"pocketbase",...extra}
|
|
*
|
|
* Usage:
|
|
* import { log } from '$lib/server/logger';
|
|
* log.error('pocketbase', 'auth failed', { status: 401, url });
|
|
* log.warn('minio', 'presign slow', { slug, n, ms: elapsed });
|
|
* log.info('auth', 'user registered', { username });
