Function set_manifest_component 

pub(super) fn set_manifest_component(
    export: &mut BundleExport,
    key: &str,
    entries: Vec<Value>,
) -> Result<(), String>

Register entries under components.<key> in the export’s manifest (bundle.json).

Takes JSON values rather than paths: most components are a list of archive paths, but projectInstructions carries an object per file, because a bare path could not express the owner discriminator that keeps import from installing somebody else’s instructions.

The manifest is built as an inline json! literal in bundle_export.rs with no struct behind it (export_bundle), so every agent-aware component has to reopen and rewrite it. Shared by the memory splice below and the history splice, which otherwise duplicated the find-parse-rewrite dance byte for byte.

No-ops on an empty list: components keys are all optional, and writing "history": [] would assert “this archive has an empty history” where absence already says “none”.
