Locator.rows() — header-keyed table extraction as List<Map<String,String>> #53

Problem

Locator.elements() (src/main/java/com/seleniumboot/locator/Locator.java:301-305) returns matched WebElements but nothing in Locator understands <table> structure. Extracting an HTML table today means raw nested findElements loops (thead for headers, tbody tr for rows, td per row) with manual index bookkeeping to zip each cell to its header — there's no helper anywhere in Locator or BasePage for this.

Why it matters

Every table-driven test re-implements the same header-to-cell zip logic by hand.

Proposed API

// Locator.java, terminal actions section, built on top of elements()
public List<Map<String, String>> rows() {
    // resolve this locator to a <table> (or a container of rows),
    // read header text from `th` (or first `tr`) as the map keys,
    // then for each body row zip cell text to the matching header key
}

// usage
List<Map<String, String>> data = $("table#results").rows();
assertThat(data.get(0).get("Status")).isEqualTo("Active");

Acceptance criteria

• Locator.rows() added, built on elements()/existing resolve machinery (not a parallel implementation)
• Header row detected via th cells (fallback: first tr if no thead/th present — decide and document the exact rule)
• Each returned Map is ordered by header column (use LinkedHashMap) with cell text trimmed
• Mismatched row/column counts handled without throwing an unrelated exception (define behavior: pad, truncate, or throw LocatorException with a clear message)
• Unit tests covering: header-only, missing thead, ragged rows, empty table
• Javadoc with a usage example matching the style of the other terminal actions in this file
