feat: Add company mode for organizational knowledge base

[divo12]

Summary

Adds a first-class company run mode to Stratiki for queryable organizational knowledge. Company mode uses the existing local-wiki, book, and connector infrastructure but operates from a dedicated Stratiki home (~/.stratiki) instead of ~/.openwiki.

What's Changed

New company mode

• Added company to OpenWikiRunMode type alongside personal and code
• Company mode writes to ~/.stratiki/wiki (configurable via STRATIKI_HOME)
• Company mode uses ~/.stratiki/book.db for the episode store

CLI Updates

• Added stratiki company positional command
• Added --mode company flag support
• Updated book commands to accept --mode <code|company> (defaults to code)
• Updated help text and examples to document company mode

Implementation

• Added stratikiHomeDir, stratikiCompanyWikiDir, stratikiBookDbPath to config
• Added ensureStratikiHome() for company mode directory initialization
• Updated getRunModeCwd() to return company wiki dir for company mode
• Updated runBookCommand() to support mode-specific book dir and DB paths

Documentation

• Updated README with three-mode table showing code, company, and personal modes
• Updated help content with company mode commands and examples

Tests

• Added tests for company mode parsing in CLI commands
• Added tests for book commands with --mode company
• All existing tests pass (12 pre-existing sqlite fts5 failures remain)

Usage

Initialize company knowledge base:

stratiki company --init

Query the company wiki:

stratiki book context --mode company "search query"

Check company book status:

stratiki book status --mode company

Design Notes

• Company mode reuses the personal mode infrastructure (book/connectors) but from a separate home
• Code mode remains the default for repository documentation
• No changes to code-wiki mode or personal mode behavior
• Small diff, matching existing patterns

Summary by cubic

Adds a company run mode for queryable organizational knowledge. Company mode reuses the existing book and connector infrastructure but writes to a dedicated Stratiki home (~/.stratiki, configurable via STRATIKI_HOME) instead of ~/.openwiki. Code mode stays the default, and existing code and personal behavior is unchanged.

New Features

• New stratiki company positional command and --mode company flag select the company brain.
• book subcommands accept --mode <code|company>; --mode company routes wiki and episode-store paths to the Stratiki home.
• Help text and README now document three modes with usage examples.

Dependencies

• Adds @changesets/cli as a dev dependency.
