Close the residual idedata and size-summary silent-failure findings

A list-of-non-dicts compile DB now raises by name inside the best-effort
tuple. The launcher rejection moved into parse_entry itself so no caller
can record ccache as the compiler, and the shape key includes the entry's
directory since relative includes resolve against it. format_bar raises
on a non-positive total so every consumer must handle the meaningless
bar; the espidf summary validates the RAM region by name (a malformed
region can no longer suppress a computable Flash line) and the blanket
backstop logs the traceback at debug. A new test pins that the CI
trigger paths exist on disk, so a rename fails loudly.
