Pi v0.79.2: experimental first-time setup flow, Bedrock validation links, and many fixes

Pi adds an experimental first-time setup flow (theme picker, analytics opt-in) and improves Amazon Bedrock data retention validation errors with direct AWS documentation links. The release also fixes over a dozen issues across context window metadata, fork chains, CJK text wrapping, Markdown rendering, and provider compatibility.

  • New: experimental first-time setup — behind PI_EXPERIMENTAL=1, prompts for a dark/light theme choice (preselecting detected appearance) and opt-in analytics data sharing on first launch, storing a trackingId in settings.json.
  • New: clearer Bedrock validation guidance — Amazon Bedrock data retention validation errors now link to AWS data retention documentation.
  • Fixes:
  • Project trust detection ignores global ~/.pi/agent state when running from $HOME; pi update uses only saved or explicit project trust without prompting.
  • Experimental first-time setup skips forked sessions.
  • OpenAI-compatible context overflow detection for parenthesized maximum context length (N) errors.
  • OpenAI GPT-5.4/GPT-5.5 and Codex GPT-5.4/GPT-5.4 mini/GPT-5.5 context window metadata to match current OpenAI limits.
  • Anthropic refusal stops preserve provider stop_details explanations in error messages.
  • OpenAI Codex Responses SSE response-header timeout increased to 20s to reduce false-positive stalls.
  • Claude Fable 5 thinking-off requests omit unsupported thinking.type: "disabled" payload.
  • Late tool progress callbacks after tool settlement are ignored instead of emitting stale events.
  • Standalone + messages no longer render as - in transcripts.
  • Slash-separated fuzzy queries keep provider/model completions matchable after insertion.
  • WezTerm Kitty image rendering reserved row clears no longer erase all but the top strip of tool image previews.
  • CJK text editor wrapping breaks at character boundaries instead of leaving large trailing gaps.
  • Loose Markdown list rendering preserves blank-line separation between items.
  • --model resolution for authenticated custom model IDs whose slash prefix matches an unauthenticated built-in provider.
  • /fork keeps session parent chains connected when the forked path contains labels.
  • /share and /export HTML exports use the active fallback theme when the configured custom theme no longer exists.
  • Custom fallback model IDs with :<thinking> suffixes preserve the requested thinking level when the provider template model does not advertise reasoning.
