What does так и не + verb mean exactly?

It means that an action was expected, intended, planned, or likely to happen, but in the end it did not happen.

A very natural English equivalent is often:

• never did
• still didn’t
• ended up not
• failed to

For example:

• Он так и не пришёл.
  = He never did come.
• Я так и не написал письмо.
  = I never got around to writing the letter.

The key idea is not just negation, but unfulfilled expectation.

Why is it так и не? Does так have a literal meaning here?

In this pattern, так и не works as a set expression. You usually should not translate так separately as so or like this.

Instead, the whole chunk так и не adds emphasis that something remained undone despite expectation.

So:

• не пришёл = didn’t come
• так и не пришёл = never did come / still didn’t come, although he was expected to

So yes, так contributes emphasis, but the safest way for a learner is to treat так и не as one grammatical unit.
