rename: chatchain becomes iota - #7

Conversation
The program is now iota (iota.sh). The name lives in ONE place —
internal/app — and everything user-visible derives from it: the binary,
the module path (github.com/joyqi/iota, go-installable at last; the old
dotless path never was), the terminal-title fallback, the cmux status
row, the MCP client name, /export file prefixes, ${appHome}, and the
~/.iota directory.
Upgrading is invisible: on first run app.MigrateLegacy renames
~/.chatchain to ~/.iota and ~/.chatchain.y(a)ml to ~/.iota.y(a)ml once
(idempotent, never overwrites, a failure only warns), announcing each
move on stderr. A project-local .chatchain.yaml is still read in place
with a nudge — it sits in somebody's working tree and is never moved.
Also: CHATCHAIN_DEBUG_REGION is IOTA_DEBUG_REGION; goreleaser pins
project_name/binary iota and the tap formula iota.rb; the Claude Code
plugin is iota@iota-marketplace with /iota:ask (2.0.0); README gains a
"Migrating from ChatChain" section; the landing page and og.png carry
the new name.

Summary
The program is now iota (iota.sh). This PR renames everything and makes the upgrade invisible for existing users.
