fix: vertico-repeat C-s and dotted-repo discovery (audit bugs)

Two bugs from the 2026-06 config audit.

- C-s C-s never repeated a search. cj/consult-line-or-repeat calls vertico-repeat on the second press, but vertico-repeat-save was never on minibuffer-setup-hook, so it always signalled "No Vertico session". I hooked vertico-repeat-save next to the vertico block. It's autoloaded, so the load defers to the first minibuffer.
- reconcile-open-repos skipped any repo with a dot in its name. cj/find-git-repos filtered children through "^[^.]+$", which matches only dot-free names, so mcp.el, capture.el, and google-contacts.el were never reconciled while M-P still reported "Complete". It now filters through directory-files-no-dot-files-regexp plus a hidden-dir guard, so dotted repos pass and .git stays out.

Each fix is test-first: a failing assertion (hook membership, three dotted repos found) precedes the change.
