docs: accuracy sweep + coverage for 2 months of shipped features

Accuracy pass (all 373 pages audited against code, 13 parallel audits):
- configuration.md: 12 stale defaults/keys (file-sync rewrite, clarify
  timeout, streaming knobs, iteration budget, TTS/STT enums)
- reference/: commands/env-vars/toolsets/tools synced with
  COMMAND_REGISTRY, argparse tree, OPTIONAL_ENV_VARS, TOOLSETS
  (28 env vars added, 3 phantom removed, mcp__ naming, webhook
  platform restricted toolset)
- features/, messaging/, developer-guide/, guides/: ~60 factual fixes
  (web_extract truncation, dashboard auth fail-closed, delegation
  blocked tools, adapter signatures, session schema v23, phantom
  Matrix env vars, hermes setup tts, auth spotify, webhook --skills)
- zh-Hans: explicit heading IDs fix 2 broken WSL2 anchors

New coverage for features shipped in the last 2 months (verified
against code before writing):
- compression.in_place, verify-on-stop (+v31/v32 migration reality),
  ${env:VAR} SecretRef, display.timestamp_format, session:compress
  hook + thread_id/chat_type fields
- /journey learning timeline, per-channel model/system-prompt
  overrides, /sessions search, clarify multi-select, -z --usage-file,
  uninstall --dry-run, config get/unset
- MCP elicitation, extra_headers, discover_models, api-server run cap,
  Bedrock cachePoint, Discord reasoning_style, Google Chat clarify
  cards, vibe reactions, resume cwd restore, Yuanbao forwarded
  messages, api_content sidecar, roaming pet, tool_progress log mode,
  WhatsApp polls/locations, kanban per-task model + lifecycle hooks
