Validate and document solana-add-idl skill: InstructionView pattern, preset regeneration test

[shahan-khatchadourian-anchorage]

Context

PR #367 updated InstructionView in the Solana parser core and fixed the skill drift in solana-add-idl. The skill update was committed in the main repo working tree but not yet merged into a PR.

Goal

Validate the updated solana-add-idl skill by using it to regenerate existing presets from scratch.

Structured test plan (3-commit PR)

1. Commit 1: update the skill (merge changes from PR fix(solana): IDL presets degrade gracefully on v0+ALT accounts #367 working tree)
2. Commit 2: delete mod.rs and config.rs for test programs (keep IDL .json files):
   • dflow_aggregator (template)
   • neutral_trade (35 discriminated instructions)
   • onre_app (38 discriminated instructions)
3. Commit 3: regenerate with the skill, commit output

Iterate until CI passes and generated output matches existing presets.

Acceptance criteria

• make -C src test passes with regenerated presets
• Generated mod.rs uses InstructionView::from_context(), no resolve_accounts()
• Generated test helpers use dummy_account_strings, not Vec
