v0.7.6 — radio message readout; 3D interaction

v0.7.6

3D world interaction (aim + walk + look-freeze)

• Working aim-based 3D interaction: select an interactable, the mod aims the player at it and walks them into range, then the game's own Interact engages it. Look-freeze holds the target while you approach and releases cleanly when you act or move.
• Softlock fixes around engaged/overlay interactions.

Radio close-up

• The radio now speaks the station's message once you tune onto a signal — when the noise resolves to readable text, the clear message is read aloud (de-duped, re-announced if you drift off and re-find it). The garbled intermediate is never read.
• "Warmer/colder" closeness cues continue to drive homing-in by ear.
• Confirmed the radio's tuning/band controls are gamepad-only in the base game, so the mod's keyboard tuning (held PageUp/PageDown to tune, Home/End for AM/FM) is the only keyboard path.

Docs

• docs/input-and-keyboard.md rewritten from the actual input asset, now documenting the complete keyboard and controller bindings for both the gameplay and UI action maps, and correcting earlier notes about which keys the game binds.
