chore(deps): bump undici and @earendil-works/pi-coding-agent

[dependabot]

Bumps undici to 8.10.2 and updates ancestor dependency @earendil-works/pi-coding-agent. These dependencies need to be updated together.

Updates undici from 8.9.0 to 8.10.2

Release notes

Sourced from undici's releases.

v8.10.2

⚠️ Security fixes

High severity

• GHSA-vp8m-p9jh-q5pm: cache and deduplication interceptors could use caller-controlled request metadata instead of the authoritative dispatcher origin, enabling cross-origin cache poisoning and data disclosure. Undici now derives interceptor identities from the dispatcher origin and bypasses origin-dependent interceptors when no authoritative origin exists. Fixed by caf6194d.
• GHSA-w293-vg96-wgc3: BalancedPool could drop function-valued connection options while cloning its configuration, including custom TLS certificate validation callbacks. Undici now preserves connect and legacy tls options when creating upstreams. Fixed by 8f5868fb.
• GHSA-rfgv-xxqx-mfg5: a WebSocket server could select a subprotocol when none was requested, causing an uncaught TypeError that could terminate the process. Undici now rejects the handshake with protocol error 1002. Fixed by 66e12816.

Medium severity

• GHSA-3wwx-pv8p-q78v: a malformed permessage-deflate payload exceeding the configured decompression limit could emit an unhandled zlib error and terminate the process. Undici now destroys the inflater after reaching the limit. Fixed by 4411a238.
• GHSA-rx4f-c7p8-82vq: an unclean WebSocketStream close could create an unobserved rejected promise when its writable stream was locked, potentially terminating the process. Undici now propagates the failure through the retained writable stream controller. Fixed by 662d0ea6.
• GHSA-2jfj-6hjv-fm6j: shared caches could store and replay responses containing Set-Cookie, disclosing one user's cookies to another caller. Undici now excludes these responses from shared caches, including existing entries and revalidation paths. Fixed by cb75bbb3.
• GHSA-3xpg-4rpp-hhhm: the decompression interceptor did not bound decoded output, allowing compressed responses to consume excessive memory. Undici now limits every decompression stage to 64 MiB by default and supports a configurable maxSize. Fixed by 7aac7f12.
• GHSA-pmjh-fq2x-6v4x: a terminal retry failure after response headers were exposed could orphan the original response body, causing consumers to hang indefinitely. Undici now propagates the terminal error to the exposed body. Fixed by e905b5b8.

Low severity

• GHSA-8436-99hf-9mmv: cache interceptors could store and replay responses to unsafe HTTP methods such as POST or DELETE. Undici now restricts cache reads and writes to safe methods while preserving invalidation by successful unsafe requests. Fixed by 2be07bf9.
• GHSA-2gqq-gqf2-x968: the dump interceptor could treat an oversized chunked response as successfully truncated when no Content-Length was present. Undici now enforces maxSize against received bytes and aborts oversized responses. Fixed by 6d583124.
• GHSA-r53p-7pc4-xj5r: the retry interceptor could concatenate a resumed response with inconsistent framing into downstream output, enabling response splitting or corruption. Undici now validates Content-Range against the original response framing before resuming. Fixed by 0160a719.

Updates @earendil-works/pi-coding-agent from 0.84.2 to 0.87.1

Release notes

Sourced from @​earendil-works/pi-coding-agent's releases.

v0.87.1

New Features

• Latest frontier models — Use Claude Opus 5.5, GPT-6 Sol, and GPT-6 Luna through supported providers, including GitHub Copilot. See Choose a Model.
• Grok 4.7 by default for xAI — New xAI sessions now default to Grok 4.7. See Provider Authentication.

Added

• Added inherited Claude Opus 5.5, GPT-6 Sol, and GPT-6 Luna support for GitHub Copilot.
• Added inherited GPT-6 Sol and GPT-6 Luna support for OpenAI API keys and OpenAI Codex subscriptions.
• Added inherited Claude Opus 5.5 support for Anthropic with adaptive thinking and a 1M context window.

Changed

• Changed the default xAI model to Grok 4.7.

Fixed

• Fixed split-turn compaction summaries being refused by Claude Fable 5.1 by clearly separating the conversation and using continuation-oriented instructions (#9908 by @​davidbrai).
• Fixed missing or invalid --mode values being silently ignored instead of reporting an error and exiting with a nonzero status (#9045).
• Fixed inherited image-only user messages being rejected by some OpenAI-compatible providers because they included an empty text part (#9797).
• Fixed inherited Anthropic OAuth requests reporting an outdated Claude Code version.

v0.87.0

New Features

• Canonical session context and extension boundaries — Edit model context without rewriting history and add actionable lifecycle hooks. See ContextEditEntry and extension events.
• Full-transcript context extensions — Use context_with_system for per-request system-message transformations. See context_with_system.
• Per-model image input limits — Configure cache-safe image resizing per model for attachments, read, and tool-result images. See Image Input Limits.

Breaking Changes

• Removed the inherited shouldStopAfterTurn agent option. Use finishTurn and return { action: "end" } instead. finishTurn runs before turn_end but applies the decision afterward, and it also receives error and aborted responses; migrate normal-response predicates by returning undefined for those hard exits. See the @earendil-works/pi-agent-core changelog for a complete before-and-after example.
• Added ContextEditEntry to the exported SessionEntry union. TypeScript consumers with exhaustive entry switches must handle context_edit; use replacement: null for omission and a content replacement otherwise.
• Made SessionManager canonical for AgentSession provider context. Assigning session.agent.state.messages no longer replaces future request history; restore with SessionManager.inMemory(cwd, { id }, entries), navigate with session.navigateTree(), or append through session.sessionManager and call session.refreshContext().
• Expanded TurnEndEvent with required boundary fields and added AgentBeforeSettleEvent to the exported ExtensionEvent union. Consumers constructing events or exhaustively switching on ExtensionEvent must handle the new shapes. ExtensionRunner.emit() no longer accepts turn_end; host integrations dispatch actionable boundaries with emitBoundary(baseEvent, buildContext).
• Deferred runs requested from agent_settled handlers until all settled handlers finish. Handlers still observe ctx.isIdle() === true, but no longer see a reentrant agent_start during the same notification dispatch.

Added

• Added append-only model-context edits. For example, sessionManager.appendContextEdit(entryId, null) omits one message from future provider context without changing raw history, usage, or UI history.
• Added actionable turn_end and agent_before_settle extension boundaries. Return { entries: [...event.entries, draft], continue: true } to persist structural entries in order and ensure one next provider request without changing steering or follow-up scheduling.
• Added retain-none compaction input: sessionManager.appendCompaction(summary, null, tokensBefore) stores the compaction's own ID as its kept boundary.
• Added the context_with_system extension event, which runs after context handlers on the full transcript including system messages and sends its result verbatim. See context_with_system.
• Added per-model image resize profiles through inputLimits.images.resize in models.json, applied to file attachments, image reads, and tool-result images (#9631).

Fixed

• Fixed string context-edit replacements producing invalid assistant and tool-result message content instead of text blocks.
• Fixed context-invisible boundary metadata and replacement edits causing newly appended or replaced input to be summarized before its first provider request.
