Pass catalog arrays to jq as files, not arguments

[neo-sky]

The release workflow has failed on every push to main since the catalog reached 28 tools carrying both schema and prompt artifacts:

./scripts/generate-manifest.sh: line 204: /usr/bin/jq: Argument list too long

No release has been cut since, so the catalog is frozen at release-2026-08-05-105 and #271's prompt-doc artifacts cannot reach the signed catalog.

The cause is MAX_ARG_STRLEN, the 128KB cap on a single argv entry, not ARG_MAX. ARG_MAX is 2MB on the runner and the whole catalog is ~173KB, which is why the error reads as impossible until you notice the limit applies per argument. The tools array crossed it once tools started carrying schemas and prompts together.

Both arrays now reach jq as files via --slurpfile instead of --argjson. Temp files go to mktemp -d with a trap, deliberately not $STAGING, whose contents are uploaded as release assets.

Verified by reproducing the failure directly: a 150010-byte single argument fails with the same error under --argjson and succeeds under --slurpfile. Every other --argjson in the script is a number, a single artifact, or bounded by an existing cap (32 schemas, 64 prompts, 256 bundle files), so the final aggregate was the only unbounded one.
