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.

+## Stucklaunch assist
+
+- Optional Movement feature; Active is off by default.
+- While engaged it holds jump, alternates +use every 2 ticks to regrab a
+  physics prop, optionally alternates +attack while the gravity gun is
+  active, and air-strafes the hops.
+- Engagement comes from `m_hGroundEntity`, latched for ~0.5 s so the prop
+  stays "active" during each hop. If that netvar is unavailable it runs
+  whenever the feature is active, so bind it to a key.
+- It does not spawn or move props. The player still supplies the prop and the
+  small initial speed. Pallets and brush physboxes work best.

 ## Roadmap / TODO
 
-- **GUI**: replace/augment the VGUI ISurface menu with an immediate-mode GUI
-  (Dear ImGui or a custom implementation); needs a design grill first.
-- **Server-side spread/recoil control**: optional single-player writes to the
-  pistol accuracy penalty and view punch, and a true zero-cone hook if wanted.
+- **Stucklaunch tuning**: use-spam period, prop class coverage, and a possible
+  pause/unpause variant still need in-game testing.
+- **Server-side spread/recoil control**: not planned; recoil and accuracy
+  penalties are intentionally left stock.
 - **Distance weapon spread thesis**: addressed by Spread control; stock HL2
   hitscan damage is range-independent, so distance efficiency is the cone.
