Mark the quotations of netdoc output and fix the stale ones
Four quotations had drifted from what the program prints: two dropped the
row cross-reference the summary ends with, the captive-portal one was cut
short, and the encrypted-DNS one was lowercased to fit mid-sentence. Each is
now the sentence diagnosis.go actually builds, with a trailing elision where
the wiki deliberately stops short.
Every quotation of program output now carries a netdoc-output marker, which
the site build checks against diagnosis.go. Five of them were restructured to
begin their own block, because an HTML comment on its own line would
otherwise split the paragraph around it.
Documentation-Map documents the convention and no longer claims nothing tests
these pages.
Remove em dashes across the wiki
Match the repository, which no longer uses them anywhere. Rewrite each
sentence rather than swapping the character.
Seven of these were not style: they quoted banner sentences the program
no longer prints, so they now match diagnosis.go again.
The six verdict headings lost their dashes too, which changes the anchor
GitHub derives from each one. Each keeps an explicit anchor at its old
slug so links already published elsewhere still land.
Add explanatory wiki
Twelve content pages plus sidebar and footer, covering usage, diagnosis,
architecture, the simulator, Challenge Mode, hunts, and contributing.
The wiki owns explanation only. Exact flags, defaults, exit codes, and
inventories stay in the repository, where they change in the same commit as
the code and are enforced by tests. Documentation-Map records that boundary.
No repository document was moved, shortened, or duplicated here; in
particular the wiki contains no literal challenge ids, since the test that
keeps those current cannot see these pages.
