docs: restore Textile's multiverse loom guide

[deepfates]

Summary

• restore branching generation and provider-free archive reading as first-class Textile paths
• separate current operations, graph/export reference, and interface rationale
• restore the implemented floor-to-MAP handoff rationale while labeling remaining motion as candidate work
• remove the obsolete SRCL migration checklist after the runtime dependency was removed

Verification

• git diff --check
• 22 local Markdown targets resolve
• 87 focused tests passed across archive intake, raw/indexed Lync, exports, provenance, controls, auth, and generation routing
• scripted Playwright browser path downloaded the synthetic kept-conversation artifact, verified 2,951 bytes (1e905074...14eef), and reimported it in a fresh context with keep and source identity intact

Stack dependency

This PR intentionally targets codex/textile-docs-base-fdedaf8, the exact existing local product commit fdedaf8. Remote main is still 93b6d32; the four intervening reader/presentation commits are not part of this documentation diff. Retarget or land this PR only after that product base is accepted. Do not merge before independent review.

Disclose the all-interface development bind

When bun run dev is used on a LAN-reachable machine, server/vite.ts binds the HTTP server to 0.0.0.0, not localhost, and development permits protected API access without an auth token. This wording can therefore lead an operator to expose the application—and, when configured, chargeable OpenRouter generation—to other hosts while believing it is loopback-only. Either document the all-interface bind and required precautions or change the server to bind localhost outside Replit.
