bump(mcpp.plugins): 0.6.0 adds the dist-* family and embed table()

0.6.0 introduces a third member family. The prefix states which of three
questions a member answers: `rules-*` how a translation unit is compiled,
`tools-*` what the build program does itself, `dist-*` what comes out of the
link and in what form a user installs it. A `dist-*` member compiles nothing
and does nothing while the build program runs; it consumes link outputs
through a `role = "artifact"` action, reached with `mcpp pack --format <name>`.

Three dist members ship: `dist-appimage` (Linux), `dist-wix` (Windows) and
`dist-apple` (macOS). `mcpp.tools.embed` gains `table()`: N inputs, one
header, one table, each row carrying its input's key alongside the contents.

The floor remains documentation rather than a gate, unchanged. Nothing here
records a per-package engine floor and index-level `min_mcpp` does not move.
What an older client gets is legible at the point of use, and for these three
members it is the best case of that rule: `mcpp::provides_pack_format` does
not exist in an older engine's bundled `mcpp` module, so a consumer that
activates a `dist-*` feature fails at the build.mcpp compile naming the
missing function rather than at a link or, worse, in an artifact.

The descriptor points at the source archive of the tag. The CN asset holds
the identical bytes, verified by download-back, so one sha256 names both
hosts. No package in this index pins `mcpp.plugins`, so moving `latest`
re-pins no consumer.

+-- several; neither can express the shape a shader set wants. A duplicate key is
+-- refused naming BOTH inputs, and the bytes are a numeric array rather than a
+-- raw string literal, because a raw literal cannot carry arbitrary binary and
+-- its delimiter is terminable by the input -- which is the defect in the CMake
+-- code this shape replaces.
+--
+-- THE FLOOR IS STILL DOCUMENTATION AND NOT A GATE, unchanged from the note
+-- below: nothing here records a per-package engine floor and the index-level
+-- `min_mcpp` does not move for a package. What an older client gets is legible
+-- at the point of use and is, for these three members, the best case of that
+-- rule: `mcpp::provides_pack_format` does not exist in an older engine's
+-- bundled `mcpp` module, so a consumer activating `dist-*` fails at the
+-- build.mcpp COMPILE naming the missing function, rather than at a link or in
+-- an artifact.
