fix: Improve parsing of Friendica (and other server) version formats (#376)
Previous code could return an error on Friendica version strings like
`2024.03-dev-1547`.

Fix this:

- Extend the list of explicitly supported servers to include Fedibird,
Friendica, Glitch, Hometown, Iceshrimp, Pixelfed, and Sharkey.

- Add version parsing routines for these servers.

- Test the version parsing routines fetching every server and version
seen by Fediverse Observer (~ 2,000 servers) and ensuring that the
server and version information can be parsed.

Improve the error message:

- Show the hostname with a `ServerRepository` error

Clean up the code:

- Remove the custom `resultOf` and `mapResult` functions, they have
equivalents in newer versions of the library (like `runSuspendCatching`)

Fixes #372

fix: Disable filter functionality if unsupported by the server (#366)
The previous code unilaterally enabled filter functionality. Some
Mastodon-like servers -- like GoToSocial -- do not support filters, and
this resulted in user visible error messages when connecting to those
servers.

To fix this:

- Extend the set of supported server capabilities to include client and
server side filtering.

- Disable the filter preferences if the server does not support filters
and show a message explaining why it's disabled.

Extend the capabilities model to support this:

- Fetch server software name and version from the nodeinfo endpoints
(implementing the nodeinfo API and schema)

- Extend the use of kotlin-result to provide hierarchies of Error
classes and demonstrate how to chain errors and display more informative
messages without using exceptions.

Fixes #343

fix: Calculate length of posts and polls with emojis correctly (#315)
Mastodon counts post lengths by considering emojis to be single
characters, no matter how many unicode code points they are composed of.
So "😜" has length 1.

Pachli was using `String.length`, which considers "😜" as length 2.

Correct the calculation by using a BreakIterator to count the characters
in the string, which treats multi-character emojis as a length 1.

Poll options had a similar problem, exacerbated by the Mastodon web UI
also having the same problem, see
https://github.com/mastodon/mastodon/issues/28336.

Fix that by creating `MastodonLengthFilter`, an `InputFilter` that does
the right thing for regular text that may contain emojis.

See also https://github.com/tuskyapp/Tusky/pull/4152, which has the fix
for status length but not polls.

refactor: Start creating core modules (#286)
The existing code base is a single monolithic module. This is relatively
simple to configure, but many of the tasks to compile the module and
produce the final app have to run in series.

This is unnecessarily slow.

This change starts to split the code in to multiple modules, which are:

- :core:account - AccountManager, to break a dependency cycle
- :core:common - low level types or utilities used in many other modules
- :core:database - database types, DAOs, and DI infrastructure
- :core:network - network types, API definitions, and DI infrastructure
- :core:preferences - shared preferences definitions and DI
infrastructure
- :core:testing - fakes and rules used across different modules

Benchmarking with gradle-profiler shows a ~ 17% reduction in incremental
build times after an ABI change. That will improve further as more code
is moved to modules.

The rough mechanics of the changes are:

- Create the modules, and move existing files in to them. This causes a
  lot of churn in import arguments.

- Convert build.gradle files to build.gradle.kts

- Separate out the data required to display a tab (`TabViewData`) from
  the data required to configure a tab (`TabData`) to avoid circular
  dependencies.

- Abstract the repeated build logic shared between the modules in to
  a set of plugins under `build-logic/`, to simplify configuration of
  the application and library builds.

- Be explicit that some nullable types are non-null at time of use.
  Nullable properties in types imported from modules generally can't be
  smart cast to non-null. There's a detailed discussion of why this
restriction exists at
https://discuss.kotlinlang.org/t/what-is-the-reason-behind-smart-cast-being-impossible-to-perform-when-referenced-class-is-in-another-module/2201.

The changes highlight design problems with the current code, including:

- The main application code is too tightly coupled to the network types
- Too many values are declared unnecessarily nullable
- Dependency cycles between code that make modularisation difficult

Future changes will add more modules.

See #291.
