* refactor(javascript): classify implicit execution in one owner
Add javascriptSemanticExecutionPoints, a total classification of every
runtime Babel node type into the ways its evaluation can run code without
call syntax. The member-mutation escape walk, the accessor operand
collector and the catch-source reachability check consult it instead of
their own syntax lists. Kinds those collectors have never applied are now
named in exhaustive switches rather than absent.
A guard test fails when the installed @babel/types defines a node type the
table does not classify, and unknown node types classify as unsupported
syntax rather than inert.
* test(hopper): retry cleanup after confirmed application exit
* fix(javascript): classify enumeration and catch binding effects
* fix(javascript): retain catch uncertainty for identifier reads
