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.

When resolving --model zai/glm-5, the resolver now correctly interprets
'zai' as the provider and 'glm-5' as the model id, rather than matching
a vercel-ai-gateway model whose id is literally 'zai/glm-5'.
If the provider/model split fails to find a match, falls back to raw id
matching to still support OpenRouter-style ids like 'openai/gpt-4o:extended'.
The extension system currently only forwards agent_start, agent_end,
turn_start, and turn_end events. This means extensions cannot access
streaming text (token-by-token), message lifecycle, or tool execution
progress — all of which are available to internal subscribers.
This adds forwarding for the remaining 6 agent event types:
- message_start, message_update, message_end
- tool_execution_start, tool_execution_update, tool_execution_end
These follow the exact same pattern as the existing forwarded events:
new interfaces in types.ts, exports in index.ts, and else-if blocks
in _emitExtensionEvent(). The new types are included in ExtensionEvent
and automatically flow through RunnerEmitEvent (they're not in the
exclusion list).
This enables extensions to build real-time UIs, streaming WebSocket
bridges, and other integrations that need fine-grained event access.

After compaction, context token count is unknown until the next LLM
response. Instead of showing stale pre-compaction values or heuristic
estimates, the footer now shows ?/200k.
ContextUsage.tokens and ContextUsage.percent are now number | null
(breaking change). Removed usageTokens, trailingTokens, lastUsageIndex
from ContextUsage (internal details).
Also fixed _checkCompaction() using .find() (first compaction) instead
of getLatestCompactionEntry() (latest), which caused incorrect overflow
detection with multiple compactions.
Closes#1382
Include tool parameter names, types, descriptions in a collapsible
section under each tool in the export HTML. Also adds parameters to
pi.getAllTools() return value.

rg was only downloaded lazily when the grep tool was invoked, but the
LLM often uses rg directly via the bash tool. Ensure both fd and rg
are downloaded at startup so they are available in PATH for all tools.
fixes#1348
Windows does not ship with unzip, causing fd/rg download to fail on
first run in PowerShell. Use tar (bsdtar, available on Windows 10+)
for both .tar.gz and .zip extraction. Also adds proper error checking
on the extraction result.
