topkoa cb425ed48d fix(panes): don't hide a docked pane; don't force display; restore visibility
Six more findings from CodeRabbit on #928. Three are real bugs.

1. THE CHIP HID DOCKED PANES. `_onOpened` decided "did the pane take my
   element?" from `ownerDocument !== document`. That is true for a pane in a
   pop-out window — and false for a pane moved into the DOCK, which lives in
   this very document. So docking a pane stamped `.fb-pane-detached`
   (display:none !important) onto the panel the user was looking at, and put
   the stub next to it instead of at its home.

   The element cannot answer this question — `isConnected` is true in a pane
   window, `ownerDocument` is this one in the dock. Both were live bugs. Ask
   the manager, which knows exactly what it handed to the host:
   `panes.elementOf(id)`. That holds for every host, and for reconciling after
   the fact (detail == null), which is what a plugin rebuilding its panel
   mid-pop-out triggers.

2. `.fb-paned` FORCED `display: block !important`. A panel that is
   `display:flex` or `grid` would be silently re-laid-out while detached —
   the exact opposite of "placement only", and precisely the kind of surprise
   this feature exists to avoid. Removed.

   Making a hidden panel visible is a separate job, and it now belongs to the
   manager, which does it without touching the panel's display MODE: clear
   `hidden`, and clear an inline `display:none` if that is how the panel hides.

3. VISIBILITY IS NOW RESTORED. The hosts used to set `el.hidden = false` and
   never put it back, so the docs' "core only changes placement" was a lie and
   a panel's hidden state was quietly lost. The manager stashes both `hidden`
   and the inline `display` on open and restores them on dock: a panel that was
   closed when you opened its pane from the tray goes back to being closed; one
   that was open stays open.

Plus:

- The launcher rebuilt its whole list on every panes:opened/closed — including
  the one fired by clicking a button in that list — destroying the button under
  the user's finger and dropping focus to <body>. It now restores focus to the
  toggled pane's button.
- `_copyStyles` cloned every stylesheet link, including the panes.css that
  pane.html already loads. Skip sheets the pane document already has.
- Docs: the chip may route to the DOCK, not always a window (it goes through
  detach() → the host router). `header` precedence was documented backwards —
  an explicit `header` wins. And the visibility contract above is now written
  down rather than being a surprise.

/* fee[dB]ack — detachable panes.
*
* Hand-authored (not Tailwind-scanned) so a runtime-installed plugin gets the chip
* and the dock without shipping its own stylesheet — the same reason .fb-selectable
* is hand-authored in core CSS.
*
* Z-index: the dock is a child of <body>, so it is NOT on the ladder from
* docs/plugin-v3-ui.md (transport 20, rail 30, popovers 40) — those numbers live
* *inside* #player's stacking context, and #player itself is `position:fixed;
* z-index:100` covering the viewport. A dock below 100 is invisible on the one
* screen panes exist for. Body-level ladder: #player 100 < dock 110 < toasts 120
* < modals 200.
*/
/* ── The popped-out element ──────────────────────────────────────────────────
*
* The single most important rule in this file.
*
* A plugin's panel is almost always a fixed overlay pinned to a corner of the app:
* `position:fixed; top:72px; right:18px; width:288px; z-index:99999`, with a drop
* shadow and a max-height sized against the viewport. Inside a dock card, or alone
* in a 320px window, every one of those is wrong — it would float 72px down from
* the top of its own window, still 288px wide, still casting a shadow over nothing.
*
* So we neutralise PLACEMENT and nothing else. Colours, borders, radius, padding,
* fonts, the panel's own internal layout: all untouched, because the whole promise
* of this feature is that what you popped out is what you get. */
