docs: introduce project Bible and consolidate all architecture documentation

- Create docs/bible/ with 10 structured chapters (overview, architecture,
  API, data models, collectors, parsers, exporters, build, testing, decisions)
- All documentation in English per ADL-007
- Record all existing architectural decisions in docs/bible/10-decisions.md
- Slim README.md to user-facing quick start only
- Replace CLAUDE.md with a single directive to read and follow the Bible
- Remove absorbed files: REANIMATOR_EXPORT.md, docs/INTEGRATION_GUIDE.md,
  and all vendor parser README.md files

-# Xigmanas Parser
-
-Parser for Xigmanas (FreeBSD-based NAS) system logs.
-
-## Supported Files
-
-- `xigmanas` - Main system log file with configuration and status information
-- `dmesg` - Kernel messages and hardware initialization information
-- SMART data from disk monitoring
-
-## Features
-
-This parser extracts the following information from Xigmanas logs:
-
-### System Information
-- Firmware version
-- System uptime
-- CPU model and specifications
-- Memory configuration
-- Hardware platform information
-
-### Storage Information
-- Disk models and serial numbers
-- Disk capacity and health status
-- SMART temperature readings
-
-### Hardware Configuration
-- CPU information
-- Memory modules
-- Storage devices
-
-## Detection Logic
-
-The parser detects Xigmanas format by looking for:
-- Files with "xigmanas", "system", or "dmesg" in their names
-- Content containing "XigmaNAS" or "FreeBSD" strings
-- SMART-related information in log content
-
-## Example Output
-
-The parser populates the following fields in AnalysisResult:
-- `Hardware.Firmware` - Firmware versions
-- `Hardware.CPUs` - CPU information
-- `Hardware.Memory` - Memory configuration
-- `Hardware.Storage` - Storage devices with SMART data
-- `Sensors` - Temperature readings from SMART data
