Add sqlite to mise-managed tools

[shunk031]

Why

agmsg depends on the sqlite3 CLI at runtime. Manage SQLite through mise so the runtime dependency is installed consistently without relying on apt or Homebrew.

What Changed

Added sqlite = "latest" to the CLI tools in home/dot_mise/config.toml.

Validation

Parse the mise config as TOML and confirm the sqlite tool entry.

python - <<'PY'
import pathlib
import tomllib

config = tomllib.loads(pathlib.Path("home/dot_mise/config.toml").read_text())
assert config["tools"]["sqlite"] == "latest"
PY

Confirm mise has a sqlite registry entry available.

$HOME/.local/bin/mise registry sqlite --json

Check the agmsg installer script syntax remains valid.

bash -n install/common/agmsg.sh
