Give Markdown and HTML file tabs back their Preview and Source views (#7614)

* fix(app): give Markdown and HTML file tabs back their Preview and Source views

The built-in Markdown and HTML panels own one toolbar again: file size,
line count, save status, vim mode, cursor, and a Preview | Source control
over a body that shows the rendered preview or the editor from the same
loaded content and editor model. Plain text files keep the toolbar on top.

The host no longer renders a panel switcher. Source is the built-in panel
for text files no other built-in claims, so it is never offered beside
Markdown or HTML in the picker, the Open with menu, or Settings > Files.
A line target opens the file's built-in panel in its Source view.

* refactor(app): name the shared text file panel TextFilePanel

Markdown and HTML own a Source view; they are not Source panels. The
composite in file-panels/source/panel.tsx is now TextFilePanel, and
SourcePanel is TextFilePanel without a Preview. Names only.

Client `addFilePanel` registrations become the body of a file tab. The tab stats the file, picks a
panel, and mounts it with a `PluginFile` handle; the panel reads, shows its own `Loading`, writes,
and resolves conflicts. The bar only switches panels and shows the dot the panel sets through
`tab.setModified`. Built-in panels (Markdown, HTML, Image, and Source, Paseo's editor) take the
same handle as plugin panels, so a fix to reading, watching, or writing lands in one place:
and resolves conflicts. The host has no bar and no notion of a panel's views: the Markdown and HTML
panels own their Preview and Source views, toolbar and editor buffer, and the tab only shows the
dot a panel sets through `tab.setModified`. Source is the floor for text files no other built-in
claims, never a candidate beside one. Built-in panels (Markdown, HTML, Image, and Source, Paseo's

`packages/app/src/file-panels/file/`. Do not add a host-side read or loading gate for one panel;
make that panel faster instead. Source highlights a large file on native in idle-time slices,
the lines around the opening line first.
