chore(kyberforge): move research docs under docs/research/ and update README

Separates development-time reference material from live plugin docs.
agentskillsio/, agentsmd/, and examples/skill-write/ are not shipped with
the plugin — grouping them under research/ makes that boundary explicit.
README now lists all top-level files and explains what research/ is for.

+version: "1.0"          # increment on meaningful changes to the skill
+updated: YYYY-MM-DD     # ISO date of last update
+
+# when: describes when this skill is loaded — the full trigger context.
+# More detail than the description field; not used for routing.
+when: <describe the invocation conditions here>
+
+# source: tracks content you ADOPTED from an upstream repo.
+# Adopt = you read someone else's code or docs and incorporated text or logic directly.
+# Omit this field entirely if the skill is self-authored — absence means original work.
+# Present only when content was actually taken, tracked at commit-level for upgrade reviews.
+source:
+  - repo: org/repo-name          # GitHub slug — no URL, slug is stable and searchable
+    commit: <full SHA>           # exact commit reviewed at time of adoption
+    files:
+      - path/to/file.md          # inline comment: what was taken from this file
+      - path/to/other.md         # inline comment: what was taken from this file
+    updated: YYYY-MM-DD          # date this source entry was last reviewed
+
+# references: tracks content you CITED but did not adopt verbatim.
+# Cite = you read it and it informed the skill, but nothing was copied or adapted.
+# Examples: a spec you followed, a paper that shaped the approach, external documentation.
+# Distinct from source: source = took content; references = informed by content.
