Release 3.1.0

Adds container Kill, compose restart/attach, builder interactive/tty/
entrypoint and in-place build context, custom docker-compatible CLI
(finch/nerdctl), and stdout/stderr log source tagging. Fixes inspect
parsing of numeric IPv6 prefix lengths and corrects ExecuteOnRunning
to run each command separately, after readiness, surfacing failures.

Simplify release flow: centralise version in Directory.Build.props (3…

….0.1)

Replace the GitVersion + per-csproj-override scheme that caused the
v3.0.0 release pain (oldest reachable tag wins, next-version ignored,
+semver: major suppressed) with a single-knob release model:

- Directory.Build.props: <Version>3.0.1</Version> is the only place a
  release number lives. Every packable csproj inherits it.
- Per-csproj <Version>/<AssemblyVersion>/<FileVersion>/<VersionSuffix>
  overrides removed from all 4 packable projects.
- ci.yml drops GitVersion install/execute/display steps and all
  /p:Version=... flags. A new "Read release version" step extracts the
  number via `dotnet msbuild -getProperty:Version` and feeds it to the
  tag step.
- GitVersion.yml deleted (still present on support/2.x for v2 hotfixes).

README: drop the inline What's-New block (now lives in the GitHub
Release notes), promote Quick Start to the first content section, add
a short v3.0.0 banner above Features with links to the release notes
and migration guide, refresh badges (.NET target reflects net8.0 +
net10.0; new badge for latest GitHub release).

Force 3.0.0 release: bypass GitVersion, exclude Benchmarks from pack

GitVersion in mainline mode on the merged-fdv3 master picks the oldest
ancestor tag (2.0.0 from 2016) as version source and ignores
next-version: 3.0.0; +semver: major is also suppressed by
prevent-increment-of-merged-branch-version. Result of the previous CI
run: v3 packages got first-published as 2.0.0 to the new package ids
(FluentDocker, FluentDocker.Testing.*, plus an unwanted
FluentDocker.Benchmarks).

This commit:
- Hardcodes /p:Version=3.0.0 in build + pack steps and the tag step,
  bypassing GitVersion for this one release. After 3.0.0 ships, the
  3.0.0 tag becomes GitVersion's anchor for 3.0.1+ and we revert this.
- Adds <IsPackable>false</IsPackable> to FluentDocker.Benchmarks so the
  solution-level dotnet pack stops producing a FluentDocker.Benchmarks
  nupkg.
- Makes the tag step idempotent so a re-run on the same SHA doesn't fail.
