f7ab93b068 manual: build action -> build task 
after discussing this with multiple people, I'm convinced that "build
task" is more precise: a derivation is not an action, but inert until it
is built. also it's easier to pronounce.

proposal: use "build task" for the generic concept "description of how
to derive new files from the contents of existing files". then it will
be easier to distinguish what we mean by "derivation" (a specific data
structure and Nix language value type) and "store derivation" (a
serialisation of a derivation into a file in the Nix store).

1ec8810687 Explain how Nix handles antiquotation of paths 
Specifically, explain why Nix does not _re_evaluate paths during a
`nix repl` session. This is a thing that bit me while playing around
with paths and antiquotation in `nix repl` while reading the Nix
language tutorial at https://nix.dev/tutorials/nix-language.

84bdb0e3ad address review feedback 
Mainly:
- Try to triangulate between narrative that framed this as
  a new/easy process and the need for a reference that will
  not quickly grow stale.
- Fix a ~continuity issue where the text was talking about
  "your Cachix cache" before saying that you'd need to make
  a Cachix cache to enable the installer tests.
- Adopt suggestion on titling, and nest subtitles in the
  installer test section.

a5be5e0120 doc/manual: define {local,remote} store, binary cache, substituter 
Nix veterans intuitively know what the following terms mean.  They are
used in several places in the nix documentation, but never defined:

- local store
- remote store
- binary cache
- substituter

In particular, I found the last two terms to be confusingly similar.
Let's give definitions for them.

843288a451 add subsections for objects and references 
group description of data instead of spreading it across the section.

that should help direct skimming. as it turns out, people do not
actually read any of that.

207992a71d introduce store and store objects without file system details 
this leaves open implementation details, especially about store paths
and file system objects, and allows explaining them together were it is
more appropriate. also leaves room to carefully introduce the key
insight behind Nix: applying results from programming language theory to
the operating system paradigm of files and processes.

render readably on the terminal (e.g. for `man nix` or `nix --help`)
without further intervention.

d5eea66615 introduce build tasks 
while it appears a bit much for the overview, this way we set the stage
for going directly into data types when describing the store, instead of
first having to say what build tasks are and how they relate to build
plans.

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.

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.
