* fix(cli): route error messages through ChatConsole inside patch_stdout Cherry-pick of PR #5798 by @icn5381. Replace self.console.print() with ChatConsole().print() for 11 error/status messages reachable during the interactive session. Inside patch_stdout, self.console (plain Rich Console) writes raw ANSI escapes that StdoutProxy mangles into garbled text. ChatConsole uses prompt_toolkit's native print_formatted_text which renders correctly. Same class of bug as #2262 — that fix covered agent output but missed these error paths in _ensure_runtime_credentials, _init_agent, quick commands, skill loading, and plan mode. * fix(model-picker): add scrolling viewport to curses provider menu Cherry-pick of PR #5790 by @Lempkey. Fixes #5755. _curses_prompt_choice rendered items starting unconditionally from index 0 with no scroll offset. The 'More providers' submenu has 13 entries. On terminals shorter than ~16 rows, items past the fold were never drawn. When UP-arrow wrapped cursor from 0 to the last item (Cancel, index 12), the highlight rendered off-screen — appearing as if only Cancel existed. Adds scroll_offset tracking that adjusts each frame to keep the cursor inside the visible window. * feat(cli): skin-aware compact banner + git state in startup banner Combined salvage of PR #5922 by @ASRagab and PR #5877 by @xinbenlv. Compact banner changes (from #5922): - Read active skin colors and branding instead of hardcoding gold/NOUS HERMES - Default skin preserves backward-compatible legacy branding - Non-default skins use their own agent_name and colors Git state in banner (from #5877): - New format_banner_version_label() shows upstream/local git hashes - Full banner title now includes git state (upstream hash, carried commits) - Compact banner line2 shows the version label with git state - Widen compact banner max width from 64 to 88 to fit version info Both the full Rich banner and compact fallback are now skin-aware and show git state.
