v0.86.0

Added

• process (start) names the WordPress version. It already carried the pid and the host; a trace read months later had no record of the core version it ran against, and the environment allowlist is the wrong home for a value that is neither a header nor a server variable. The line now reads <pid> on <host>, WordPress <version>.

Changed

• Show more / Show less is a control again, with its own state. Folding a row and opening its message body are separate acts on separate state: expandedSet holds pairIds, expandedBodies holds entry ns. Clicking the row folds and unfolds it and leaves the body alone; clicking Show more or Show less opens or closes the body and stops the event there, so neither one moves the fold. A search still opens the body it lands on and puts it back on the next n, and clearSearch restores both sets.
• A childless pair stays merged when a search lands on it. Opening it was only ever needed while the fold hid the body too; the body now opens on its own, so there is nothing for the unfold to reveal.

Fixed

• A search term is marked in the complete half of a merged pair. renderMergedMessage printed completeMsg raw. It went unnoticed while a search unfolded the pair it landed on, which exposed the real (complete) row; with the pair staying merged, the match the reader navigated to had no <mark> on it.
