Terminals speaking the CSI-u (kitty / fixterms) keyboard protocol -- kitty,
Ghostty, WezTerm, and terminal panes that default to it -- encode Shift+Enter
as the escape sequence "\x1b[13;2u". prompt_toolkit 3.0 has no support for
that protocol and no default mapping for the sequence, so its Vt100Parser
fails to recognise it and dumps the raw bytes ("^[[13;2u") straight into the
prompt buffer. The multiline-input work kept only Alt+Enter, so on these
terminals Shift+Enter now leaks visible escape garbage into the input.
Register "\x1b[13;2u" (absent from prompt_toolkit's default ANSI_SEQUENCES,
so setdefault() overrides nothing) and bind it to insert a newline, matching
the Alt+Enter behaviour. This is best-effort: prompt_toolkit cannot negotiate
the protocol, so we only react to a CSI-u sequence a terminal already emits;
terminals that collapse Shift+Enter into plain Enter fall back to Alt+Enter,
which stays the primary shortcut.
Add a real-PromptSession regression test asserting the sequence inserts a
newline rather than leaking raw escape bytes.

maintainer edit: Align OpenAI-compatible API auth with the WebSocket channel boundary: loopback serve remains usable without a key, while wildcard binds still fail before agent initialization unless api.api_key is configured.
maintainer edit: Check api.api_key before template sync and AgentLoop construction so missing-key startup errors are not hidden by provider or workspace initialization failures.
On terminals that send a bare LF for plain Enter (WSL is the case
prompt_toolkit itself calls out), Alt+Enter arrives as ESC + LF
("\x1b\x0a" = Escape + ControlJ), not the ESC + CR the existing
"escape","enter" binding matches. The Escape was swallowed and the bare
LF hit prompt_toolkit's default submit, so the documented "universally
supported" Alt+Enter newline fallback failed on exactly the terminal path
plain Enter is preserved for.
Bind ESC + ControlJ to insert a newline too, and add a real-PromptSession
regression test covering the WSL Alt+Enter path.

"\x1b[27;2;13~" (the older xterm modifyOtherKeys / rxvt encoding of
Shift+Enter) is already registered by prompt_toolkit by default -- as
Keys.ControlM, i.e. plain Enter/submit. The previous `setdefault()` call was
therefore a silent no-op against it: this Shift+Enter variant kept behaving
like a submit instead of inserting a newline, even after the ControlJ/WSL
fix, since setdefault only sets missing keys.
Assign directly to override that default for both known Shift+Enter
sequences, since inserting a newline is the whole point of the binding.
Add a regression test driving a real PromptSession/parser with this exact
sequence, since a mocked-buffer test can't observe prompt_toolkit's default
ANSI_SEQUENCES entries taking priority.

Keys.ControlJ is also the literal LF byte ("\x0a") that some terminals send
for a plain Enter keypress -- prompt_toolkit's own default bindings handle
this by re-feeding it as ControlM/submit, and calls out WSL by name as the
case that needs it. Binding our Shift+Enter handler to ControlJ shadowed
that default, so on any terminal sending LF for Enter, pressing Enter only
ever inserted a newline and the prompt could never be submitted.
Register the CSI-u Shift+Enter sequences against Keys.ControlF3 instead: an
enum member prompt_toolkit declares but never wires to a default ANSI
sequence or key binding, so it's only reachable through our own mapping.
Also add a regression test that drives a real PromptSession/Vt100Parser
with a raw LF byte -- the existing key-binding test invoked handlers
directly against a mocked buffer, which exercises the handler logic but not
prompt_toolkit's key-resolution precedence, so it couldn't have caught this.

The interactive prompt used a single-line buffer (multiline=False), so
there was no way to compose a multi-line message before submitting.
Switch to a multiline-capable buffer with custom key bindings: Enter still
submits (unchanged feel), Alt+Enter always inserts a newline, and
Shift+Enter inserts a newline on terminals that emit a distinguishable
CSI-u sequence for it (kitty, iTerm2 with the fixterms protocol) by mapping
those sequences onto the otherwise-unused ControlJ key.
maintainer edit: cron is also a trigger source, so keep the new CLI-delivered source explicitly named as local trigger across backend, WebUI, docs, and tests.
Remove the PR changes that made nanobot onboard default to the wizard, added --defaults, added non-TTY fallback behavior, and changed the Docker smoke command. Keep Quick Start available through nanobot onboard --wizard.
Maintainer edit: make explicit --defaults refresh existing configs without prompting when no TTY is available, preserving user values for CI and Docker runs.
maintainer edit: preserve provider-prefix CLI routing for named custom providers by stripping only the matched dynamic route prefix before sending the model id to OpenAI-compatible endpoints. This keeps ordinary namespaced model ids intact when the provider is selected explicitly.
maintainer edit: treat arbitrary custom provider names as direct OpenAI-compatible providers, validate their api_type consistently, and avoid Pydantic instance-field warnings in fallback routing.
