A hyperlink longer than 200 characters came back as a different 200-character
URL -- one that still looks like a working link -- and the import reported
nothing. It applied to a text layer's base style and to a character style
override alike.
The destination went through `clip_str`, which exists so that names and labels
from a file stay readable when they are quoted in a warning. Every other caller
is a name, a description, a style id or a layer type; a hyperlink is data, and
clipping it silently rewrote it. Two things say so: the FIG importer already
keeps the URL whole, so the two importers disagreed, and `rest::props` bounds
numbers and list lengths but no string beyond that label helper -- the text
content itself is not clipped either.
The reporter's integration test is included, with its assertions unchanged. Its
helper is restructured to return what it found rather than unwrap: the crate
denies `unwrap_used` and `panic`, and `clippy.toml` allows them only inside a
`#[test]` function, so the original shape failed the gate before it ran. Its
failure message now reports the input and output lengths.
