feat(scaffold): output deployed program IDs in generated runbooks

[michael-moffett]

Adds an output "<program_name>_program_id" construct per deployed program to the scaffolded runbooks, following the addon's _program_id naming convention; happy to switch to a single map output if you'd prefer.

Closes #339

[greptile-apps]

Greptile Summary

The PR adds a named program-ID output for each program in both in-memory and on-disk scaffolded deployment runbooks.

• Generates <program_name>_program_id outputs from each deployment action’s program_id.
• Adds a unit test covering multiple generated output blocks and their spacing.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete blocking or non-blocking issue identified.

Both scaffold paths append consistently named outputs tied to their corresponding deployment actions, and the generated multi-program output structure is covered by a focused unit test.

Important Files Changed
