feat(git): add git repository hosting command and skill

Adds `atxp git` CLI command (create, list, remote-url, delete) backed by
the git.mcp.atxp.ai MCP server. Includes a separate atxp-git skill with
documentation emphasizing the ephemeral nature of authenticated remote URLs.

feat(email): add mark-read command for explicit read status

The email service no longer auto-marks messages as read on retrieval.
This adds `npx atxp email mark-read <messageId>` to explicitly mark
messages as read using the new email_mark_as_read tool.

feat(search): add date filtering with --start-date and --end-date flags

Support startPublishedDate and endPublishedDate parameters on the
search_search MCP tool, allowing users to restrict results by
publication date. Also fixes toolArgs extraction to properly skip
flag values that would otherwise leak into the query string.
