fix(multicursor): zq failed motions, "t", first step

Problem:
- "Vjzqfx" (on a line without "x") places a cursor at the selection start.
- 'nowrapscan': `zqN` places a cursor on a non-match; `zq#` mid-word
  places it mid-word.
- `zqfa` places at primary even if not on an "a".
- `zqti` stops after one step (bc "ti" before an "i" does not move).

Solution:
- `did_beep_silent`: counts beeps silenced by `emsg_silent`, so `zq`
  steps can detect failed motions.
- If a `zq` step does not move the cursor, retry it from the next char.
- Decide the first `zq` step the same way as `{Visual}zq` already does:
  the primary is considered a step only if the motion lands on it.
