perf(protocols): import the protocol, schema and data packages lazily #2730
Description
Ruling (owner, in session): the pcapkit.protocols packages, along with their schema and data subpackages, import lazily where possible, as pcapkit.const does in the companion issue.
#2534 regroups each protocol's protocol, schema and data modules, and it moves every module these package __init__ files import. This is blocked until #2534 merges, so the two changes do not rewrite the same files at once. It then reuses the shared lazy-import helper from the const work.
- Protocol dispatch already imports the next layer by module path, so making the packages lazy should keep dispatch working. Each registry that a package's import fills in, such as the
registercalls, has to keep working. - Measure
import pcapkitbefore and after.

#2534 has landed (#2753), so this is unblocked. A fix is in progress on a branch off
1b4f9703e. It makes the layer-level and top-level protocol aggregation lazy throughlazy_exports. Each protocol package__init__keeps its literal imports, per the #2753 layout ruling. It measuresimport pcapkitfirst, and stops with a recommendation if the gain is negligible.JarryShaw commentedon Nov 4, 2026
