Add PowerShell and Bash modules for command history tracking with P2P sync

[Copilot]

Implements shell integration modules for cross-device command history tracking, deduplication, and analysis with NixOS/WSL support.

Modules

PowerShell (modules/powershell/)

• 11 functions: init, query, frequency analysis, session/host stats, config
• Profile integration via PSReadLine hooks
• WSL hostname detection

Bash (modules/bash/)

• 15 functions: equivalent to PowerShell + NixOS/WSL-specific features
• Integration via DEBUG trap and PROMPT_COMMAND
• macOS/BSD timestamp fallback for cross-platform compatibility

Database Schema

CREATE TABLE command_history (
    command TEXT, hostname TEXT, shell_type TEXT,
    timestamp INTEGER, duration_ms INTEGER, exit_code INTEGER,
    session_id TEXT, device_id TEXT,  -- P2P sync fields
    UNIQUE(hostname, shell_type, command, timestamp)
);

-- Views: command_history_unique, command_frequency, failed_commands, 
--        session_history, host_summary

Indexed by hostname, shell type, timestamp, and session for efficient cross-device queries.

Usage

# PowerShell
Import-Module PluresDB
Enable-PluresDBHistoryIntegration
Get-PluresDBHistory -CommandLike "git*" -SuccessOnly -Last 20
Get-PluresDBCommandFrequency -Top 10

# Bash
source /path/to/pluresdb/modules/bash/pluresdb.sh
pluresdb_enable_integration
pluresdb_history --command-like "git" --failed-only
pluresdb_nixos_rebuilds  # NixOS-specific

Security

• SQL injection prevention via input escaping (doubled single quotes)
• Input validation with [ValidateRange] on numeric parameters
• Regex special character escaping in ignore patterns
• Documentation on sensitive data handling (passwords in command args)

Platform Support

• Windows: PowerShell 5.1+, Core 6.0+
• Linux: All major distros, NixOS-specific features
• macOS: BSD-compatible date handling
• WSL: Cross-platform command tracking

Documentation

• docs/COMMAND_LINE_INTEGRATION.md (16KB): Complete reference
• docs/CLI_INTEGRATION_SUMMARY.md: Implementation overview
• Example scripts for both shells

<issue_title>Refine and document pluresdb command line integration</issue_title>
<issue_description>Add pluresdb powershell and bash module implementing advanced features, data entry and retrieval, data cleanup, manipulation, database setup and configuration, and database troubleshooting and analysis utilities.

Add easy cmd history integration, whereby powershell history and transcripts are automatically routed to pluresdb and retrieved from pluresdb once configured. Implement history dedup view that shows unique cmds, cmd grouping and sorting, and support simplified queries which can return cmds of type or like, which ended in error or were successful, to include command to return output and just the cmd or both.

Include nixos integration for advanced nixos troubleshooting.

Index all system integrations by hostname and shell type so synced database could allow accessing cmds, history, transcripts, etc, from different machines, or different shells.

Also support wsl. </issue_description>
