/**
 * Export manifest — validation rules and entry point.
 *
 * Implements 10 validation rules that operate on {@link ExportManifestInput}
 * and produce structured {@link ExportManifestIssue}s.
 *
 * Rules:
 *  1. Invalid manifest version  — error if version is not valid semver
 *  2. Missing source project    — error if sourceProjectId is empty
 *  3. Missing generated timestamp — error if generatedAt is empty
 *  4. Missing purpose           — warning for each artifact without purpose
 *  5. Empty file                — error for each artifact with fileSize === 0
 *  6. Stale file                — warning for each artifact flagged stale
 *  7. Checksum mismatch         — error when expected checksum != actual
 *  8. Missing required file     — error when expected artifact not found in output
 *  9. Unexpected file           — warning when output file not in expected set
 * 10. Wrong file type           — error when artifact type doesn't match expected
 * 11. Missing artifact metadata — error/warning for missing checksum, size, or generator data
 * 12. Manufacturing roles       — error when required board outline, drill, or layer roles are missing
 * 13. Project metadata          — error when EasyEDA/project metadata is required but absent
 * 14. BOM/PNP consistency       — error when pick-and-place designators are not represented in BOM

/**
 * Run all export manifest validation rules against an input manifest.
 *
 * Orchestrates 10 rules:
 *  1. Invalid manifest version   — error if version is not valid semver
 *  2. Missing source project     — error if sourceProjectId is empty
 *                                — warning per artifact without sourceProject
 *  3. Missing generated timestamp— error if generatedAt is empty
 *                                — warning per artifact without timestamp
 *  4. Missing purpose            — warning per artifact without purpose
 *  5. Empty file                 — error per artifact with fileSize === 0
 *  6. Stale file                 — warning per artifact with stale === true
 *  7. Checksum mismatch          — error when checksum "expected:actual" differs
 *  8. Missing required file      — error when expected artifact not in output
 *  9. Unexpected file            — warning when output file not in expected set
 * 10. Wrong file type            — error when artifact type !== expected type
 * 11. Required metadata        — error when manufacturing policy requires missing checksums, sizes, or generation metadata
 * 12. Manufacturing roles      — error when required board outline, drill, layer, BOM, or pick-place roles are missing
 * 13. Project metadata         — error when EasyEDA/project metadata required by policy is absent
 * 14. BOM/PNP consistency      — error when assembly designator data is inconsistent
