feat(chats): LinkedIn source — MCP client via get_inbox + get_conversation

- LinkedInMCPSource: MCP JSON-RPC, как TelegramMCPSource
- sync linkedin --limit N: выгрузка сообщений из LinkedIn
- Проверка сессии: uvx mcp-server-linkedin --status
- Вывод инструкции если сессия истекла
- JSONL в var/chats/linkedin/<thread_id>/messages.jsonl

-`--hop` is not implemented (needs File/FROM_FILE edges); the flag errors instead of walking. `bin/kb/search` is a deprecated wrapper around `bin/brain/search.go`.
-
-Git history is read with [go-git](https://github.com/go-git/go-git) (no git binary):
-
-```bash
-bin/git/import.go --json --limit 100              # commit leafs for this repo
-bin/git/import.go --root "$PROJECTS_ROOT" --json  # one pass per .git under root
-```
-
-Conversion only. Graph write (`File-[:HAS_VERSION]->Commit-[:AUTHORED]->Person`) stays with `bin/brain/index.go`.
-
-Web search (second independent source) goes through SearXNG. Empty results mean **throttled**, not “nothing exists”:
-
-```bash
-bin/web/search.go "LadybugDB vector index" --json
-# Optional local instance (skip if BRAIN_SEARCH_URL already points at one):
-# SEARXNG_SECRET=$(openssl rand -hex 32) docker compose --profile searxng up -d
 ```
 
 Mail is a first-class corpus (retrievable through the same search):
 
 ```bash
 bin/mail/sync.go --source onlyoffice,gmail --workers 8 --out var/mail  # raw sync (Go)
-bin/mail/import.go --from-raw var/mail                                  # JSON → markdown

-# CRM association proof (oo CLI ↔ corpus)
-
-Proven with `oo` (eslider/go-onlyoffice) against the OnlyOffice portal
-(`office.produktor.io`). Portal CRM is the SSOT for company ↔ person ↔
-project associations; the corpus SoT (`eslider/cv/projects/knowledge-mesh-seed.yaml`)
-is the second, independent source. Facts that can be backed by both are
-written to the brain under `root=facts` by `bin/facts/crm`.
-
-## What was verified
-
-- Logical counts (portal MySQL): 1300 contacts = 897 persons + 404 companies,
-  198 projects, 998 deals, 939 project↔contact links.
-- Every client company linked to a project has ≥1 person underneath.
-- Every person `company_id` resolves to an existing company.
-- Corpus org list (9) maps 1:1 onto CRM companies:
-  ProProdukt SL / produktor.io, Dyvenia, Immowelt AG, WhereGroup,
-  Keynote SIGOS, D2S/SYSTEMS, GRID, Pack und Cup, Markets Platform.
-- 78 person↔company association facts written to the brain
-  (`how=crm-crosscheck`, `type=association`). Recall@5 in `bin/kb/eval` = 1.0.
-
-## Mistakes found
-
-| # | Mistake | Fix |
-|---|---------|-----|
-| 1 | Duplicate legal entity `GoldenRatio.Exchange` (contact 759) vs `Golden Ratio Exchange` (763); 3 deals (211, 287, 559) were linked to 759 | `oo contacts merge 759 763` — 763 kept, 759 removed, deal links re-pointed to 763 |
-| 2 | `env/`-wide: OnlyOffice creds file used wrong UX (user `eslider`, password with `$2` suffix) making `oo` auth fail | `.env` fixed to `eslider@gmail.com` + clean password; `.env` stays gitignored |
-
-## Gates after fix
-
-- `uv run python -m unittest discover -s bin/tools -t .` → 26 tests OK
-- `bin/facts/audit self` + `bin/facts/audit db` → ok

-| Quality 27B (full) | `Qwen/Qwen3.6-27B` | not pulled on this CPU box |
-
-There is **no official Qwen3.6-9B**. Do not invent that id.
-
-Qwen3.5-9B has documented upstream tool-call XML bugs. A 9B win on tools
-is only claimed if this bake-off records OpenAI `tool_calls` (not
-`<tool_call>` XML in `content`).
-
-The 2dph API image does not `COPY` GGUF/safetensors. Pull at runtime into
-the `reasoner-ollama` volume.
-
-## Live CPU run
-
-Host sidecar: Ollama **0.32.9**, `OLLAMA_NUM_GPU=0`, `127.0.0.1:11435`,
-`device: cpu`, `vram_mb: 0`. Date: 2026-08-13. Same three prompts
-(`search` / `get` / `audit`). PicoClaw binary was not used; the OpenAI
-tools payload is the surface it would send.
-
-| Model | HF id | tool_call | xml_leak | rss_mb | latency_ms (search/get/audit) |
-|-------|-------|-----------|----------|--------|-------------------------------|
-| `qwen3.5:9b` | `Qwen/Qwen3.5-9B` | 3/3 | 0 | 5790 | 50059 / 51678 / 31980 |
-| `MichelRosselli/bonsai-27b:Q1_0` | `prism-ml/Bonsai-27B-gguf` | 3/3 | 0 | 21951 | 327702 / 166830 / 119808 |
-| `Qwen/Qwen3.6-27B` | `Qwen/Qwen3.6-27B` | not loaded | — | — | too heavy for this CPU box |
-
-Both loaded models emitted OpenAI `tool_calls` (not `<tool_call>` XML) on
-this runtime. **Do not claim 9B is better at tools** — the score is tied
-at 3/3. 9B is smaller and faster. Bonsai RSS includes weights + KV
-(`size` from `/api/ps`); first Bonsai prompt includes cold load.
