Resolve allocation-backed mplace locals and display their allocation
contents with dump_alloc.

Keep unsupported provenance as <indirect> and update the fixtures for the
temporary diagnostic allocation output.

Automatic Rustup

Replace the diagnostic dump_alloc output with a Priroda-owned byte renderer
for mplace-backed locals.

Compute the current value size with size_and_align_of_val, inspect only the
mplace byte range, and render uninitialized bytes with an explicit marker.

Render complete pointer provenance while dumping indirect local values.
Preserve initialized and uninitialized byte ranges, including padding and
partial pointer bytes, and report unsupported unsized values explicitly.

Add UI coverage for pointer positions, nonzero target offsets,
uninitialized regions, and partial provenance.

Add a `follow` command that renders allocation bytes starting at a given
allocation offset, reusing the provenance-aware allocation byte renderer used
for indirect locals.

Document the command and cover following a rendered pointer allocation in the
pointer-rendering UI test.

When using `RUSTFLAGS="-Ctarget-features=+avx512f"`, the Rust compiler
complains:

    error: unknown codegen option: `target-features`

The actual option uses the singular form.

Add a CLI fixture covering a projected memory-backed field inside a larger
aggregate. This locks in that projected values render only their own MPlace
layout bytes instead of trailing bytes from the parent allocation.

Keep projected MIR Places long enough to evaluate them with
`eval_place_to_op`, then reuse the existing raw operand renderer for
immediate and memory-backed values.

This removes `<unsupported-projection>` from projected locals, including
fields, enum projections, references, and dereferences. Update the projected
debug-info UI expectations and verify the full Priroda suite.
