rename accessibilitySnapshot to snapshot for shorter agent usage

The function is now exposed as `snapshot()` in the executor sandbox scope.
`accessibilitySnapshot` remains as a backward-compatible alias pointing to
the same function, so existing agents and saved commands continue to work.

Updated all code examples across skill.md, README, PLAYWRITER_AGENTS,
docs, tests, and the extension welcome page to use the shorter name.
