fix(coord): drop unused snip-threshold constants, name elision margin

Two dead module-level constants flagged by github-code-quality on
PR #529: ``_INSPECT_MSG_SNIP_THRESHOLD`` and
``_INSPECT_TOOL_ARG_SNIP_THRESHOLD`` lost their callers when the
content-snip logic moved into the ``_snip_head_tail`` helper.  The
helper now reads ``head + tail + _INSPECT_ELISION_MARGIN`` so the
"reserve bytes for the elision marker" rationale that the dead
constants documented stays named instead of becoming a bare ``64``.
