Fix tooltip truncation; add Stucklaunch assist

Tooltips: text_in() shifted the x position to fit the full string before
truncating, which drew the tooltip text outside its box. Truncate to the
available width first, then clamp inside the clip.

Stucklaunch (Movement):
- opt-in feature (Active off by default) with its own bind;
- holds jump, alternates +use every 2 ticks to regrab a physics prop,
  optionally +attack while the gravity gun is active, and air-strafes;
- engagement uses m_hGroundEntity (client netvar) latched for ~0.5 s so the
  prop stays active while airborne; falls back to running whenever active if
  the netvar is unavailable, with a startup warning to bind it;
- does not spawn or place props; the player supplies the prop and initial
  speed.

Config gets [stucklaunch] active/bind/use_spam/gravspam/autostrafe; Reset
restores those defaults. CONTEXT documents the assist and its limits.
