docs(readme): use absolute URLs for logo images (#63)

* docs(readme): use absolute URLs for logo images

Use https://raw.githubusercontent.com/<org>/<repo>/main/... for logo
references so they render on crates.io. Relative paths render correctly
on GitHub but are dropped by the crates.io README sanitizer, leaving a
broken image at the top of every crate page.

* ci: pin actions to full-length commit SHAs

Org policy "all actions must be pinned to a full-length commit SHA" was
rejecting CI runs at the workflow setup step. Pin every uses: ref to a
40-char SHA, with the original tag preserved as a trailing comment for
human readability.

For dtolnay/rust-toolchain and taiki-e/install-action, the action's
required input was previously inferred from the ref (@stable, @nextest);
since SHA-pinning loses that signal and the action errors out without
the input, an explicit `with: toolchain:` / `with: tool:` is added.
