M0: compilable skeleton — Kigi 0.1.0 fork surgery

Hard fork of xai-org/grok-build (Apache-2.0) re-targeted as Kigi, an unofficial Kimi Code CLI community build. Rename & identity - 72 xai-*/xai-grok-* crates -> kigi-* (explicit: xai-grok-pager-bin -> kigi-bin [binary `kigi`], xai-grok-pager -> kigi-tui; rest mechanical); ptyctl, ptyctl-cli, third_party/ unchanged; proto package xai.grok.tools.v1 -> kigi.tools.v1 - Config home ~/.kigi (KIGI_SHARE_DIR override), env prefix GROK_* -> KIGI_*, `kigi --version` carries the unofficial-community-build notice - clap identity, help text, startup banner, prompt templates rebranded (templates re-encrypted) Deletions (PRD removal list #5/#6/#7/#9/#10) - voice input (xai-grok-voice) and all TUI wiring - telemetry: Mixpanel client, external OTel stream, Sentry, OTLP layers, trace/GCS/S3 upload queues (kigi-file-utils halved), workspace upload module & dc_log, heap-profile uploader, auth-diagnostics uploader, session-analytics halves of feedback; local zero-egress observability preserved in new kigi-log crate (unified log, --debug firehose, subsystem file logs, opt-in instrumentation) - announcements (crate, remote-settings fields, TUI surfaces) - plugin marketplace (crate, sources/browse/CTA/extensions-modal tab); direct plugin install/uninstall/update via kigi-agent git_install kept - relay/gateway/assets endpoints and features (agent relay, headless relay transport, gateway bridge, LeaderEnvUrls); leader IPC socket now ~/.kigi/leader.sock + KIGI_LEADER_SOCKET, no ws-url derivation - functional types rehomed instead of deleted: PermissionMode -> kigi-config-types, McpInitStrategy -> kigi-mcp, PrCreationSource -> session signals, TerminalDiagnostics -> kigi-pager-render, agent_id -> shell util Endpoints - kigi-env rewritten: single production KigiEndpoints {coding_api_base_url https://api.kimi.com/coding/v1 (KIGI_CODE_BASE_URL), oauth_host https://auth.kimi.com (KIGI_OAUTH_HOST), update_base_url (GitHub Releases API), upgrade_page_url}; GrokBuildEnvironment enum deleted Toolchain & workspace hygiene - Rust 1.97.0 pinned; edition 2024; full cargo update; git2 hoisted to workspace at 0.21 (Option->Result API migration), quick-xml 0.41 - Root Cargo.toml hand-maintained (PRD §8.1): version 0.1.0 inherited by all members, members sorted, unused deps pruned - cargo-deny advisories gate (deny.toml with documented transitive exceptions); CI workflow (check/clippy/fmt/deny/test, macOS+Linux) - cross-crate test seams re-gated behind `test-support` cargo feature; insta snapshot baselines renamed to the kigi_tui prefix - clippy --workspace --all-targets: zero warnings; fmt clean Fixes surfaced by the port - updater probe/installer divergence (bin/kigi vs bin/grok symlink set) - idle model-metadata refresh dead under KIGI_CODE_BASE_URL override (new is_effective_coding_endpoint_url, loopback+override aware) - macOS symlinked-TMPDIR fixture canonicalization (foreign_sessions, fast-worktree); RSS measurement tests serialized via serial_test Docs & legal (Apache §4) - NOTICE added (upstream attribution + change statement); THIRD-PARTY notices sustained; kigi-tools ported-code notices extended; README, CONTRIBUTING, SECURITY, AGENTS.md rewritten Out of scope for M0 (tracked): Kimi auth/inference (M1), search/fetch, command parity, config import (M2), Computer Hub excision & final brand-token sweep (M2), distribution & self-update rewrite (M3).

+//! Linux system sleep/wake via systemd-logind's `PrepareForSleep` D-Bus
+//! signal, with a `delay` inhibitor lock so we get a short window to react
+//! before the system actually sleeps.
+//!
+//! Uses the `zbus` blocking API on a dedicated thread so we don't require the
+//! caller to run any particular async runtime. If the system bus or logind is
+//! unavailable (non-systemd distro, container, permission error), `start`
+//! returns `None` and the caller degrades gracefully.
