New POST /sessions/:key/chat endpoint that speaks the Vercel AI SDK
UI message SSE protocol (x-vercel-ai-ui-message-stream: v1). Accepts
both useChat format ({ messages: UIMessage[] }) and simple gateway
format ({ text: string }). Streams text-start, text-delta, text-end
events through the existing session infrastructure.
Add configurable initial filter mode for the session tree navigator.
Users who always switch to a specific filter (e.g. no-tools via Ctrl+T)
can now set it as default in settings.
Same pattern as doubleEscapeAction (#404). Filter infra from #747.
Use visibleWidth/truncateToWidth for footer path and stats truncation so wide Unicode text cannot overflow terminal width.
Add regression tests for wide session/model/provider names and document the fix in changelog.

The previous fix (83b57924) replaced require.resolve() with bare
specifier fallbacks to avoid ERR_PACKAGE_PATH_NOT_EXPORTED for ESM-only
packages like pi-ai. However, bare specifiers are not valid jiti alias
targets, breaking extension loading in global npm installs.
Use import.meta.resolve() as the fallback instead. It respects the
"import" exports condition and returns a real file path.
When enabled, /tree navigation skips the 'Summarize branch?' prompt and
defaults to no summary, reducing friction for users who never want branch
summaries.
Closes#1791
GNU screen does not support truecolor escape sequences. When pi emits
truecolor SGR sequences (e.g. \x1b[38;2;102;102;102m for the dim color
#666666), screen misparses the semicolon-separated parameters as
individual SGR codes. The RGB value 102;102;102 maps directly to
SGR 102 (bright green background), which then bleeds into every
subsequent \x1b[2K line-erase, producing a bright green background
on most info/status messages.
detectColorMode() now returns '256color' for any TERM value that is
'screen', starts with 'screen-' (e.g. screen-256color), or starts
with 'screen.' (e.g. screen.xterm-256color). The existing COLORTERM
check at the top of the function already handles the opt-in case for
users who have configured screen's truecolor passthrough.
Messages submitted while a branch summary was being generated were
processed immediately instead of being queued. This happened because
isCompacting only checked compaction abort controllers, not the branch
summary abort controller.
Include _branchSummaryAbortController in the isCompacting getter so all
existing guards (message queueing, reload blocking) also apply during
branch summarization.
createBranchedSession() wrote the file and set flushed=true even when the
branched path had no assistant message. The next _persist() call saw no
assistant, reset flushed=false, and the subsequent flush appended all
in-memory entries to the already-populated file, duplicating the header
and entries.
Fix: defer file creation when the branched path has no assistant message,
matching the newSession() contract. _persist() creates the file on the
first assistant response.
