SendMessage lets extensions inject messages into the conversation and
trigger new agent turns, enabling async patterns like background
subagent execution. It delegates to app.Run() which handles queueing.
CommandDef.Execute now receives Context so commands can access
SendMessage, Print*, and session metadata. The UI layer wraps the
call via runner.GetContext() at the boundary.
Also fixes all 20+ golangci-lint issues across the codebase:
errcheck, modernize (min/max/slices.Contains/SplitSeq/range-over-int),
staticcheck (error string casing), and unused code removal.
Replace catwalk dependency with direct models.dev integration (97 providers,
3039 models vs catwalk's 22/679). Auto-route @ai-sdk/openai-compatible
providers through fantasy's openaicompat using the api URL from models.dev,
eliminating the need for --provider-url. Add --all flag to 'mcphost models'
to show all providers vs just fantasy-compatible ones.
Fix all 74 golangci-lint issues: errcheck (53), staticcheck SA4006 (24),
SA9003 (2), ST1005 (5), ineffassign (3). Restructure styles.go color
handling into a colorScheme struct to eliminate SA4006 false positives
from new(x) syntax.
Each spinner created a new tea.NewProgram which sent DECRQM queries for
synchronized output mode 2026. When the program exited and restored
cooked terminal mode, the terminal's DECRPM response leaked as visible
^[[?2026;2$y characters. Replace Bubble Tea spinner with a simple
goroutine animation loop writing directly to stderr via lipgloss.
