refactor(core): align cli with hardened core/go reference shape

Audit verdict: COMPLIANT across all 25 dimensions including the new
stdlib-name-aliases dimension.

Started at 746 findings; converged to 0. 77 files, +5858/-10625 (heavy
net delete of dead/banned code).

Notable changes:
- Production code converted to core wrapper / Result shape
- AX-7 dump files removed; tests/examples redistributed into per-source
  <file>_test.go siblings
- AGENTS.md, docs/architecture.md, docs/development.md authored
- vet/test issues from the Result conversion fixed
- No type-alias dodges, no stdlib-name aliases, no stdlib shadow packages

+# Agent Notes
+
+This repository is the `dappco.re/go/cli` module. It provides the shared command-line runtime, terminal UI helpers, daemon helpers, package commands, and i18n utilities used by Core command tools.
+
+Work in this repo should follow the v0.9 Core conventions:
+
+- Import `dappco.re/go` as `core` when a file needs Core wrappers.
+- Keep public-symbol tests in the sibling `<source>_test.go` file using `Test<File>_<Symbol>_{Good,Bad,Ugly}`.
+- Keep public-symbol examples in the sibling `<source>_example_test.go` file.
+- Prefer `core.Result` for fallible production functions so callers branch on `r.OK`.
+- Do not put compliance tests in aggregate AX-7 files or versioned test files.
+
+The CLI package mutates process-level state for stdio, theme, colors, and global runtime registration. Tests that touch those globals should restore them with `t.Cleanup` or the local reset helpers before returning.
+
+Before handing work back, run:
+
+```sh
+GOWORK=off go mod tidy
+GOWORK=off go vet ./...
+GOWORK=off go test -count=1 ./...
+gofmt -l .
+bash /Users/snider/Code/core/go/tests/cli/v090-upgrade/audit.sh .
+```
