The crate README rewrite was unrolled at eval time: one sed block per
crate, each carrying one -e expression per other crate. The installPhase
string grew with the square of the crate count, and at 40 crates
(d5de1e494 added swarm-claude-login) it reached 131708 bytes. Linux
caps a single environment variable at 128 KiB, so exec of the builder
failed with "Argument list too long" and every consumer of
reference-docs failed with it, the website repo included.
The rewrite is now a shell loop over $members at build time, building
the same sed expressions per crate. The phase text no longer depends on
the crate count. Output is byte-identical to the old form at 6aab2ebb6
(39 crates, the last commit where it built).
Closes#5321
