install.sh: CLI file sends + OSF shorthand in agent context

The installed AGENTS.md / CLAUDE.md now document the headless file-send
form and teach agents that "OSF" is user shorthand for omarchy-send
("OSF report.pdf to gav" → omarchy-send -to gav report.pdf).

 The target is matched against the peer's display name, case-insensitively. The
 command discovers the peer over multicast and, like the TUI, directly probes
 your known peers and online Tailscale peers (waiting up to `--wait`, default
 15s) — so a remote box added with `+` in the TUI, or any tailnet peer, is a
-valid `--to` target from a script too. It sends the message, prints a one-line
+valid `--to` target from a script too. It sends the message and/or files,
-result, and exits non-zero if the peer isn't found or the send fails. It starts
+prints a result line per file, and exits non-zero if the peer isn't found or

-`omarchy-send` instance is up. Both `--to` and `--message` are required; file
+run while another `omarchy-send` instance is up.
-sending stays in the TUI for now.
+
+`--to` requires a `--message`, file/folder paths, or both (flags must come
+before the paths). A folder is sent whole and its structure recreated on the
+receiver. Paths *without* `--to` instead open the TUI with them pre-staged
+(quick-send) — that form needs a TTY.
