Initial extract: templates + methodology guide from Ideation

Public, version-controlled source of truth for TeamIDE's project
templates, coding conventions, and the build-plan → PM scaffolding
rules. Mounted read-only by TeamIDE's planner agent at runtime.

Extracted from the personal Ideation repo as a precondition for
workspace-projects-agent-spec.md §9.4. Personal Ideation stays
private; this repo holds only the publishable methodology.
