Construct the universe-controlled affinoid Berkovich point model

[dagurtomas]

Parent

Subtask of #21, split from draft PR #34. Comparator targets were added in d960950.

Goal

Construct a universe-controlled topological point model for an affinoid Berkovich spectrum.

Comparator targets

• BerkovichSpace.affinoidPointTopCat
• BerkovichSpace.affinoidPointHomeomorph

Scope

For a strict affinoid algebra in the ground-field universe, construct a TopCat.{u + 1} point space, likely by lifting the relative Berkovich spectrum and transporting its topology. Prove it homeomorphic to BerkovichSpectrumOver K A with the canonical residue norm and normed-algebra instances.

This issue deliberately excludes the structure sheaf and global Berkovich-space assembly.

Acceptance criteria

• No point-only object is presented as a completed Berkovich space.
• The topology is transported canonically and the universe levels match the comparator.
• Production files contain no sorry.
• Focused, root-import, comparator, and full Rigid builds pass.
