[REHEARSAL] scaffold: emit a program-id output block per program

[michael-moffett]

DO NOT MERGE. Rehearsal PR on the fork, opened to exercise CI against a base literally named main. The upstream-facing change is tracked at solana-foundation#339.

Base is caliperforge/surfpool@main, fast-forwarded to upstream tip e3b7df0e. Diff is one file, crates/cli/src/scaffold/mod.rs.

Greptile Summary

The PR extends generated deployment runbooks with one program-ID output block per deployed program.

• Adds a shared output-template helper referencing each deployment action's program_id.
• Emits outputs in both in-memory and on-disk scaffold paths.
• Adds a unit test covering multiple output blocks and blank-line separation.

Confidence Score: 5/5

The code change appears safe, although the PR description explicitly marks this rehearsal pull request as not intended for merging.

The generated output blocks consistently use the same program metadata supplied to the corresponding deployment-template calls, and the investigation established no reachable contract, syntax, or runtime failure.

Important Files Changed
