ztheme 1.6.0

# ztheme shell integration
#
# Synchronous prompt segments (directory, command status, prompt character,
# user custom segments) are computed in Zsh during `precmd` through the
# generic `_ztheme_compute_sync_segments` dispatcher and held. Git and runtime
# values are styled in Rust and arrive as finished fragments from the per-shell
# `ztheme __client-daemon` process. The complete prompt is assembled and drawn
# in one atomic redraw once those fragments finish or the shared deadline
# expires.

# Bundled segments are embedded assets shipped inside the binary. Custom
# segments were validated and allowlisted by the ztheme binary and are sourced
# here, once, during initialization; nothing in this section runs per prompt.
#
# Custom definitions are emitted first and bundled definitions afterward so
# bundled segment functions win under ordinary redefinition.
