2303f84a68 revert to "build plan" in overview diagram 
this displays correct composition again. build inputs and build results
are not part of build plans in terms of data objects.

also this is a much less complicated setup. this will be the first
impression of architecture, and we want to get it right.

0e63b9bf88 add link from overview to store section 
the overview should only link to the three main concepts presented. the
store is now fairly fleshed out. others can follow later.

902638c519 build step -> build rule 
"step" sounds atomic, while "rule" hints at internal structure, which in
our case consists of mapping inputs to outputs using build instructions.

5fda995491 formalize file system objects 
convention: describe every data type in prose, and illustrate with
a class diagram, and a textual representation of an abstract
data type.

right now we save ourselves the trouble of doing class diagrams, we can
add them later. but they are important.

fb2ec7e4ec reword section on references 
use file Contents instead of Data, as that flows more naturally in the
prose.

simplify explanation of the idea behind scanning for store paths

remove references to unfinished sections.

7598126391 remove separate meta-section, add architecture diagram 
the diagram is a first approximation and only covers that same section.
of course there is much more going on, and other features should at some
point also be illustrated.

we also have to think about presentation format and technicalities
behind it. the manual has to render to `man`, but we may want something
more refined for web view.

of contents.

b387d80943 remove sentence for chapter transition 
idea: sections could be read in different orders by linking them in
different ways (e.g. depth-first or breadth-first). adding hard-coded
transitions makes that confusing.

few things best I could based on @edolstra's corrections, and a Bazel
glossary.
