 Add notes to docs from Discord and office hours discussions (#36) 
* Add community insights from Discord threads and meeting notes

Distill Discord discussions (Feb 14-24) and Feb 26 office hours into
existing docs:

- New findings: NimbleBrain skill:// resource consolidation, skill
  reliability/adherence issues across implementations
- Expanded approaches with distribution/provenance considerations,
  resources adoption insight, and domain-level discovery (.well-known)
- Expanded open questions on dependencies and distribution trust
- Added Cloudflare Agent Skills Discovery RFC and NimbleBrain
  reference implementations to related work

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Remove trust note since its already mentioned in the doc separately

* Clarify attribution for community insights on skill dependencies in open questions

* Refine findings on model skill adherence and community workarounds

* Remove outdated comparison section and streamline evaluation insights in experimental findings

* Remove unnecessary blank line in experimental findings documentation

* Add SEP-2093 proposal to related work documentation

Defines an `index.json` discovery index with progressive disclosure (name/description at discovery time, full SKILL.md on activation), SHA-256 content integrity, and optional archive distribution. Complementary to MCP-level discovery: `.well-known` answers "what skills does this domain publish?" while MCP answers "how does the agent consume them at runtime?"
