Add why-and-when doc: value proposition and decision guide (#62)

Browse source 
* Add why-and-when doc explaining value proposition and decision guide

Adds docs/why-and-when.md covering why skills over MCP matters (same
channel as tools, discovery, dynamic updates, control model, multi-server
composition, enterprise distribution) and when MCP distribution adds
value vs simpler alternatives. Linked from README and problem-statement.

* Add why-and-when summary to README before problem statement

Gives newcomers the value proposition immediately: skills are context,
MCP is a context protocol, and remote MCP servers can serve tools and
know-how together. Links to the full doc for depth.

* Add portable sub-agent point to why-and-when doc

Skills over MCP replaces the pattern of independently wrapping each
MCP server in a custom sub-agent with hand-written instructions —
the server author ships orchestration guidance once, everyone benefits.

* Acknowledge enterprise trust trade-offs in both directions

Address PR feedback: git-based and MCP-based skill distribution each
raise different governance concerns. Link to open question on security
and trust boundaries.
