refactor: make the offline Pester suite able to fail (#153) (#205)

Skip-IfMissing skipped a test whenever the cmdlet under test was absent
from the build, including the test asserting it exists. Every cmdlet
compiles into one assembly, so there is no partial-build case for it to
serve; all it did was hide a missing cmdlet. Delete the 37 copies and
every call site, and drop the residual conditional skips in the same
family (CmdExists probes, an attribute-presence skip in SdnCmdlets, a
lifecycle helper skipping on a cmdlet-name collision fixed long ago).

894 It blocks only reflected [Cmdlet] and [Parameter] attributes back at
the compiler: existence, CommandType -eq 'Cmdlet', Parameters.ContainsKey,
IsMandatory reflection, and per-file CmdletsToExport asserts for whichever
names an author remembered. Nothing reflected over the built assembly, so
a new cmdlet missing from the manifest shipped invisible. One data-driven
file replaces them: it diffs CmdletsToExport against the assembly's cmdlet
types in both directions and asserts the conventions reflection can see.

Behavioural tests are untouched: no-session errors, binding rejections,
ShouldProcess and -WhatIf, ConfirmImpact, ValidateSet and ValidateRange
values, parameter types, positions and pipeline binding.

The generated help covered 169 of 194 cmdlets. Regenerated with the repo's
own generate-help.ps1: 25 new markdown stubs, 13 existing docs picking up
parameters added in earlier waves, and a rebuilt MAML.
