Add docs/ folder and slim down README

Claude CLI uses the first line of command files as preview text. With the
marker at the top, every skill showed "<!-- generated by CodeCanon/sync.sh..."
instead of useful context. Moving it to EOF lets the invocation header show
in the preview instead.

Also adds backward compatibility: read_file_info detects markers at both
positions (end=current, start=legacy) and forces regeneration of legacy files.

The initial implementation set body_hash=None for legacy files, which
caused them to be flagged as "customized" and skipped. Instead, compute
the real body_hash and return a needs_migration flag so sync_skill can
force a rewrite even when content hashes match.

Move sync marker to EOF for better CLI preview

Document label and milestone expectations for /start and /qa in
README and setup skill; add template comments. Regenerate Claude
commands. Require git pull before /version step.
