iris 3c262b6c1b docs: rename docs/components to docs/crates
The generated landing page's own H1 already said "Crate reference" —
the directory name should match. Rename docs/components/ -> docs/crates/
and update the generating derivation (nix/packages/reference-docs.nix),
its default.nix caller comment, and docs/README.md's link.

Fixes #3193

# The repo `docs/` markdown tree, shipped as a standalone derivation so
# agents can read the reference docs in-container (added as a claude
# additional directory by the harness) WITHOUT pulling the branding +
# prompt assets they don't need, and so the `hyperhive/website` repo can
# reuse the exact same tree as a flake input.
#
# The docs/ tree is copied verbatim (never transformed). On top of that,
# `$out/crates/<crate>.md` is synthesized — one per workspace crate
# with a README.md, virtualized under docs/ (mara's ask: "behaves as if
# hive-core/README.md lives at docs/crates/hive-core.md"). The
# crate's own README stays the single source of truth; this derivation
# only projects it into the docs tree, so there is no second copy to keep
# in sync by hand. `docs.nix` (website repo) needs no changes to pick these
# up — it already walks every subdirectory + `.md` file generically.
#
# Output layout:
# $out/ — the repo docs/ tree verbatim (e.g. $out/setup.md)
# $out/crates/<crate>.md — one per workspace crate README, plus the
# hand-written docs/crates/README.md
# landing page (copied verbatim like any
# other docs/ file, not generated here)

# rather than a fresh `lib.concatMapStrings` per crate's own transform —
# every crate needs the exact same substitution list (every *other*
# member), so this only differs on the `member != other` filter.
