diagnose: investigate Miruro launch discrepancy

 After selection, the browser starts in **normal mode**. Press `i` to type a search; Enter submits a changed query and returns to normal mode. Esc returns without submitting.
 
+In either provider's normal mode, press `p` (`app.provider`) to reopen the chooser with the current provider selected, then Enter to switch. Esc cancels and returns to browsing (unlike at startup); `q` or Ctrl-C quits. Both browser sessions stay in memory, preserving their queries, results, selection and navigation history when you switch back. Switching leaves running players unaffected and never reapplies the CLI query: it is used only for the initially opened provider. `--miruro` only skips the startup chooser; you can still switch providers with `p`.

 Both providers use the same layout: a cyan view heading, bordered search and results, a bordered status line, and a dim one-line key hint bar. Entries use two lines: the title above dimmed metadata. YouTube shows the channel and publication date beneath each video title, without separate channel/date columns; tagged channels remain cyan. The selected row uses black text on cyan with a `> ` marker; saved titles are green, watch-later titles magenta, and `✓` marks watched entries. Metadata and help open in centered cyan-bordered popups; bulk-removal confirmations use yellow borders. Miruro keeps its catalog navigation and title/episode metadata.
 YouTube's dimmed metadata row includes duration as `M:SS` or `H:MM:SS`, or `Unknown duration` when unavailable. Duration is retained in saved collections; older entries without duration remain readable.
