* feat(stacks): copy stack anatomy as Markdown
Add a "copy md" action to the Stack Anatomy panel that exports the parsed
compose summary as a deterministic Markdown document: services, ports and
volumes tables, restart policy, env file with its variable count, missing
variables, network, and source. Useful for pasting a stack's wiring into a
README, a Git repository, Obsidian, BookStack, or a support thread.
The export carries only env variable names and counts, never the values
stored in .env files.
* fix(stacks): escape backslashes in anatomy Markdown table cells
escapeCell escaped pipes but not the backslash itself, so a backslash in a
cell value (for example a Windows path) could defeat the pipe escaping and
break the rendered table row. Escape the backslash first, then pipes, then
collapse newlines. Adds a regression test.
* fix(stacks): correct git source attribution and CR handling in anatomy export
Gate the Anatomy panel's git source on its owning stack so a slow git-source
response for a previously selected stack can no longer render or be exported
under a different stack. Also collapse lone carriage returns (not just CRLF and
LF) in Markdown table cells so a stray CR cannot break a table row.
