Aim_Training: gameplay + accessibility improvements (scaling, TTL, keyboard, HUD, localStorage)

[sufiya0412]

…culty scaling, bubble TTL, accuracy/combo, pause/restart, localStorage high score, container-bound spawns)

PR Description 📜

What does this PR do?

• Fixes HTML entity comparison issue and timer duplication.
• Keeps bubbles within the container (responsive positions).
• Adds difficulty scaling (faster spawns; slightly shorter TTL).
• Adds bubble TTL + miss handling (resets combo).
• Adds accuracy & combo HUD (optional spans shown if present).
• Adds keyboard (Enter/Space) and touch support.
• Adds Pause/Resume (P) and Restart (R) shortcuts.
• Persists high score via localStorage.
• Small README notes for controls & accessibility.

Why is this needed?

• Improves gameplay variety, accessibility, and overall UX.
• Reduces bugs (no multiple timer intervals; safe spawns).
• Keeps changes self-contained to Aim_Training.

Notes

• HUD elements (accuracyValue, comboValue, muteToggle, status-live) are optional; script degrades gracefully if missing.
• Audio is optional; script checks for audio elements.
• This PR improves an existing game and does not add a new game entry, so gamesData.json and the main GameZone README were not modified.
