docs(skills): clean up 6 makers-agents reference doc defects

[vincentism]

Upstream review of edgeone-pages-skills flagged six non-blocking issues that we inherited via the earlier synchronization. All confirmed in this repo; none affect runtime behavior, but they break rendering, links, or runnable examples:

• framework-native-patterns.md: three dead links (langchain-route.md, claude-sdk-route.md, platform-conventions.md — none exist). Repoint to the current targets: node-frameworks/langgraph.md, node-frameworks/claude-sdk.md, platform/node-entry.md.
• python-frameworks/crewai.md /history handler: signature is handler(context) but the body used ctx.conversation_id (would NameError). Rename to context.conversation_id.
• python-frameworks/crewai.md Node/Python compare table: the memory row said "typically replaced by ctx.store" — softer than the body's memory=False hard constraint. Align to "Must be memory=False; cross- turn memory goes through context.store".
• python-frameworks/crewai.md See also: drop the empty leading list item.
• platform/node-entry.md externalize-packages table: a blockquote line cut the table body, leaving the bcrypt row orphaned outside. Move bcrypt into the table, keep the blockquote after.
• capabilities/store.md framework compare table: the Bare model / custom loop cell had an unclosed **, which broke that row's rendering. Close the bold marker.
