Identity the cursor wire presents

What it does

Decides which identity the cursor wire presents to its host, as D521 did for three other hosts: a live probe under an honest name, then either a row in D521's table with the measurement or a recorded reason the borrowed value stays.

Against the three criteria

• Direction (README): The README says nothing about provider wires (README.md:6-8 names the vendors' CLIs).
• Today's terminal users: The wire sends cursor's own CLI version, borrowed, as x-cursor-client-version on every request (crates/ganja-provider/src/provider/cursor.rs:148, crates/ganja-provider/src/provider/cursor.rs:570).
• Evidence: Cursor has no row in D521's table. The probe needs a live turn on a stored sign-in.

Depends on

Nothing. The live probe is the owner's to run.

Verdict

• Verdict: do
• Size: S — one commit, no plan; the live probe is the owner's to run.
• Exception to the probe rule: yes. #36 says an idea that needs a measurement or a probe first is not do; this one is an explicit exception: the live probe is part of the work and is the owner's to run.

Theme: #57

Start in crates/ganja-provider/src/provider/cursor.rs at lines 148 and 570, and read the existing handling of the borrowed x-cursor-client-version value. Run the live probe on a stored sign-in under an honest name, then compare the result with D521's table. Done means recording a measurement row or documenting why the borrowed value remains.
