* feat(model): add `picoclaw model add` for custom OpenAI-compatible endpoints
Onboards a model from a user-supplied API base + key by hitting
GET <base>/models, prompting the user to pick one, and writing the entry
into model_list[] (with api_keys) plus setting it as the default model.
This was previously only available in the TUI launcher (issue #2208) and
is now accessible from the CLI:
picoclaw model add -b URL -k KEY [-m MODEL] [-n ALIAS]
* chore: remove deprecated picoclaw-launcher-tui
Per RFC #2208, the TUI launcher is deprecated in favor of the CLI; its
"online model picker" feature has been ported to `picoclaw model add` in
the previous commit. This drops the binary and all build/release/docs
references:
- delete cmd/picoclaw-launcher-tui/ and assets/launcher-tui.jpg
- Makefile: remove the `build-launcher-tui` target
- .goreleaser.yaml: drop the build entry plus the `picoclaw-launcher-tui`
ids from the launcher docker image, macOS notarize list, and nfpms
contents
- docker/Dockerfile.goreleaser.launcher: drop the COPY for the TUI binary
- READMEs (root + 8 locales): remove the "TUI Launcher" section and
screenshot link
- docs/guides/docker.*: update the "launcher image includes …" sentence
to reflect the two remaining binaries
`make build` still succeeds; `go build ./web/backend` (the launcher
target) still succeeds. `picoclaw-launcher` (web console) is unaffected.
