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).

+# 0.2.52
+
+## Features
+
+- **Tool auto-approval (YOLO)** state is now tracked end-to-end in server-side agent sessions.
+- **ER diagrams** now render as entity boxes with attributes and relationships in the TUI.
+- New "Respect manual folds" setting keeps hand-expanded blocks stable while content streams in.
+- **Ctrl+X** now stops running turns or closes sessions from inside the agent detail view.
+- **Grok** can now export usage metrics and events to your own OpenTelemetry collector when enabled.
+- **WezTerm users** now receive guidance when Shift+Enter fails because kitty keyboard protocol is disabled.
+- **Long-running sessions** now tell the model when the local calendar date changes past midnight.
+- **Agent Dashboard** now works without leader mode and shows local idle sessions from disk.
+
+## Bug Fixes
+
+- **Fixed oversized session replay logs** that prevented large sessions from loading.
+- **MCP server connections** no longer flood reconnects on repeated stream errors.
+- **ZDR and team upload flags** are now populated immediately on login instead of only after background refresh.
+- **Mermaid PNG export** now handles quoted cardinalities in class diagrams and readable ER rows on dark theme.
+- **Skill catalog** no longer shows duplicate "Use when:" labels and check-work skill now prompts the model to read its instructions.
+- Compaction now rejects overly-short summaries that would discard real conversation state.
+- Background tasks no longer emit spurious failure messages when a session is resumed.
+- **Fixed Windows path handling** so external tools and model prompts receive clean paths without \?\ prefixes.
+- **Images and media** no longer remain visible when switching from an agent view to the dashboard.
+- **Clipboard paste** (Ctrl+V) now works for images on pure Wayland sessions.
+- **Modals** such as /sessions no longer crash on narrow terminals.
+- **ptyctl resize** now correctly notifies the child process.
+- **Concurrent updates** to the same version no longer fail with permission or EEXIST errors.
+- **Mermaid diagrams** containing CJK or other non-Latin text now render correctly instead of tofu boxes.
+- **`grok dashboard`** now reliably opens the dashboard instead of silently falling through to a normal session.
+- **Sessions** no longer remain blocked forever after a transient model catalog outage during reconnect.
+- **Cancel** no longer leaves the interface stuck on "Cancelling…" after lost responses during reconnects.
+- **Forked sessions** now retain the parent's full pre-compaction transcripts instead of only the compacted summary.
+- **web_fetch** errors on GitHub hosts now recommend using the gh CLI when internal access is blocked.
+- **MCP server connections** no longer hang when stdio servers emit undecodable lines.
+- **Ctrl+C cancels** now complete in under 50 ms instead of blocking for seconds.
+- **Repeated varied edit failures** on one file no longer trigger doom-loop warnings or terminations.
+
+## Performance
+
+- **Compaction** now reuses cached prompt prefix instead of full prefill.
