chore(repo): remove agent and planning documents from the repository

The repository is public and should carry only shippable source,
licensing, and operator documentation. These files are internal working
documents that were never intended for publication.

Removed:

- AGENTS.md, the agent operating instructions.
- MESH_AGENT_1_SECURITY_PRIVACY_RECOVERY_2026-07-31.md
- MESH_AGENT_2_VOICE_NETWORK_OPERATIONS_2026-07-31.md
- MESH_AGENT_3_PRODUCT_DESIGN_ACCESSIBILITY_2026-07-31.md
- MESH_IMPLEMENTATION_COMPLETION_REPORT_2026-08-01.md
- MESH_PRODUCTION_READINESS_CONTINUATION_2026-08-01.md
- MESH_SOL_PRODUCTION_IMPLEMENTATION_PLAN_2026-07-31.md
- MESH_SOL_REFERENCE_REPOSITORY_PRODUCTION_PLAN_2026-07-31.md
- PRODUCTION_BETA_PLAN.md

.gitignore drops the allowlist entries that kept those documents tracked,
and pre-emptively ignores mesh/audit/ and mesh/docs/product/reinvention/
so the screenshot and mockup artifacts produced on feature branches are
never published here.

No tracked file referenced any removed document.
