fix: move run-install-scripts under runtimes.node

[Copilot]

run-install-scripts only affects npm install commands, which are exclusively generated by the Node.js runtime. Having it as a top-level frontmatter field was misleading — it belongs under runtimes.node.

Parser / types

• Remove RunInstallScripts *bool from FrontmatterConfig (top-level struct)
• Drop frontmatter parameter from resolveRunInstallScripts() — only runtimes.node.run-install-scripts and the merged-imports flag are checked
• Remove hasTopLevelRunInstallScripts() from import_field_extractor.go

Schema & generated docs

• Remove top-level run-install-scripts from main_workflow_schema.json
• Regenerate frontmatter-full.md and autocomplete-data.json

Before / after

# before (top-level)
run-install-scripts: true

# after (nested under runtimes.node)
runtimes:
  node:
    run-install-scripts: true

Codemod

The migration is implemented as a Go codemod (getRunInstallScriptsToRuntimesNodeCodemod) registered in the fix command registry, so it runs automatically via gh aw fix. It handles all cases:

• No runtimes: block → appends a new runtimes.node block
• runtimes: exists without node: → inserts a node: sub-block
• runtimes.node exists → injects the field into the existing block
• Both top-level and nested forms present → removes the top-level duplicate (idempotent)

@copilot the codemods must be implement in go and run as part of the fix command

@copilot please implement the Go codemods and report any remaining blockers.

Done. The codemod is now implemented in Go as getRunInstallScriptsToRuntimesNodeCodemod() in pkg/cli/codemod_run_install_scripts.go and registered in GetAllCodemods() so it runs automatically as part of gh aw fix. The JS script has been removed.

The codemod handles all migration cases:

• No runtimes: block → appends a new runtimes.node block
• runtimes: exists without node: → inserts a node: sub-block
• runtimes.node exists → injects the field into the existing block
• Both top-level and nested forms present → removes the top-level duplicate (idempotent)
