Type short fills in video mode

[mmkal]

What changes

videoMode() now shows short locator.fill() values arriving character by character.

videoMode(); // type short fills in the recording
videoMode({ typeFills: false }); // keep Playwright fill behavior

Non-empty values up to 100 characters are cleared, then typed with a 50 ms delay per character. Empty, longer, and forced fills keep Playwright's original action. Highlights and metadata still describe the caller's fill().

The renderer uses the real field pixels from the typed action over its stable pre-action frame. This keeps the text animation without replaying unrelated page effects.

Before

The email field stays empty for the text hold, then jumps to the complete value.

After

The same unchanged test now shows ada@example.com arriving character by character.

Validation

• One new public-behavior spec covers default typing and typeFills: false
• Existing expectations are unchanged
• 75 tests passed; 3 provider-gated tests skipped
• Typecheck, build, and publint passed
