mcp-inspector --version starts the web server instead of printing the version #2632

Problem

Found by the 2.10.0 release smoke (#2623); the same in 2.9.0. mcp-inspector --version falls through to the default web mode, binds 6274 and prints a token URL. --cli --version fails with "Method is required", and --tui --version fails with "unknown option". Only mcpdo --version prints a version (2.10.0).

Expected

mcp-inspector --version (and -V) prints the package version and exits 0 without starting anything. --cli and --tui should do the same.

Priority

Low (rubric total 5): Severity 2, Urgency 1, +1 bug, +1 milestoned.
