This commit adds @override decorators to approximately 300 methods
across 76 files that inherit from base classes such as AbstractCmd,
FileContext, ExecContext, Distro, SSHClient, and others.
The decorator ensures the type checker can verify that overridden
methods have compatible signatures and prevents accidental shadowing
of inherited methods without intent.
Files modified include command classes, library modules, distro
implementations, and SSH client implementations.

Add new ruff rules and fix their fallout:
future-annotations = true
select = [
"TC", # type-checking import placement rules
"FA", # future annotations rules
]
This comprises:
- Streamline imports and exports in cmds.xxx.Cmd
- Import base class as "Base"
- Export types Cmd and Parent via __all__
- Move all types imported only for annotation below TYPE_CHECKING
- Use "from __future__ import annotations" all over the place

The previous commits have put rules for linting and formatting via
ruff, yapf, mypy and pyright into place. They are checked with the
make check target, and this commit adds the fixes for the target to
succeed.
It does some refactoring where type checking dug up dirty bits, and
also adds lots of churn in the Python code. To a good deal, that's
owed to mere formatting changes. It would have been better to
seperate those from syntax and refactoring fixes into multiple
commits, so that the interesting changes don't drown in the
formatting nose. However, that would have been a lot of additional
work only to be thrown away by later commits, hence this commit has a
big diff in one piece. The size of the diff is regrettable but
hopefully a one-off: What it buys is automatic format checking for CI
and predictble formats for smaller diffs in the future.
Rules that "make check" enforces are, in the following order
- Syntax checkers:
- ruff check .
- mypy .
- pyright
- Format check:
- yapf --diff --recursive .
The refactoring includes:
- Turn the Result class into a more elaborate object, capable of
doing more heavy lifting around stderr and stdout decoding,
summarizing outcome, and matching error strings.
Aside from fixing broken type checks, this also removes lots of
boilerplate calling code which is currently used for handling
possible call outcome scenarios. Trying to access an inexistent,
decoded string should raise a meaningful exception by itself now,
which removes lots of code with case distinctions.
- Fix Cmd type hierarchy:
- Add the AbstractCmd class above Cmd. This is necessary because
the checker rightfully complains it can't instantiate a Cmd
instance where constructor arguments were needed. They never
were, but the type used at the instantiating code's location in
jw.pkg.App so claims.
- Lots of sub- and sub-subcommands are derived from the base
class of the invoking command. That provides some properties
shared across the ancestor hierarchy of a command, but is
semantically unsound. Fix that by introducing jw.pkg.BaseCmd
class as a place to provide basic helpers shared across all
commands used in a jw.pkg.App's context, and derive all command
classes from that afresh. The parent command is still reachable
via a common parent property.
Formatting changes are conforming to PEP-8, mostly, with minor
tweaks. All in all they include the following changes.
- Remove # -*- coding: utf-8 -*-
The line was needed by Python 2 which is not supported anylonger.
For Python 3, the default encoding is UTF-8, anyway.
- Allow to run "make py-format" without having it produce any
changes. It's basically "yapf --in-place --recursive ." with some
code style settings, see conf/topdir/pyproject.toml. The settings
may be debatable. I've had custom tweaks in place on that target,
too, but then again, IDEs would have more hassle to integrate
that.
- Introduce a 88 character line length limit
- One import per line, reshuffle them semantically, see
[tool.isort] in pyproject.toml.
- Hide imports needed for type-checking only behind
if TYPE_CHECKING
- Spaces around assignments accounts for much churn. Having having
no spaces in inline parameter list assignments and default
parameter values would arguably be more compact where it's
useful. On the other hand, I have not found a code formatter
which allows spaces around assignments in parameter lists broken
into one per line and that's often better than a wall of text.
- Add two spaces before # export, as this seems to be mandated by
PEP-8
- Use single quotes by default

Cmd._run(), as conceived for working with lib.App, is meant to be an
async method. To be conservative about changes, jw-pkg's legacy way
of handling _run() was kept when deriving from libApp, and async was
not propagated down to the _run() implementations. This commit
rectifies that before adding additional subcommands.

During __init__(), commands have no idea of their parent. This is not
a problem as of now, but is easy to fix, and it's architecturally
desirable to be prepared just in case, so add the parent argument to
the ctor before more commands are added.

Reorganize the Python module structure. Placing the command classes
under jw.cmds.projects instead of jw.build.cmds will allow to add a
nested command structure, with the current commands, being mostly
related to building software, found below a "projects" toplevel
command.
Other conceivable commands could be "package" for packaging, or
"distro" for commands wrapping the distribution's package manager.
