BirdEcho v0.5.4

Fixed

• Nachtzuster fork: no detections shown — when display_limit is a numeric parameter (which the app always sends), Nachtzuster's todays_detections.php packs all row content (time, common name, scientific name, confidence, audio player) into a single <td> instead of the four-cell layout used by mcguirepr89. The parser's cells.length < 4 guard skipped every Nachtzuster row, resulting in an empty feed. The parser now detects single-cell rows and extracts each field with targeted regexes (<b><a class="a2"> for common name, <i> for scientific name, HH:MM:SS pattern for time, N% for confidence). (#20)

• Nachtzuster fork: Species tab empty — fetchTopSpecies called /play.php?getlabels=true, which returns raw BirdNET model labels in the format "Turdus migratorius" (scientific name with spaces, no underscore, no common name). The code expected "Sci_Name_Common Name" format and skipped every label when indexOf('_') === -1, returning an empty species list. For Nachtzuster, the species list is now derived directly from today's parsed detections (which carry both common and scientific names), eliminating the broken API call. (#20)
