zshrs 0.11.0

# zshrs-daemon bash wrappers
# ==========================
# Bash-canonical version of daemon-shell.zsh — same surface, identical
# semantics. Source from your ~/.bashrc:
#
#     source /path/to/daemon-shell.bash
#     daemon-ping
#     id=$(daemon-job-submit -- find / -name '*.zsh' 2>/dev/null)
#     daemon-job-status "$id"
#     daemon-job-output "$id"
#
# bash 3.2+ compatible (the macOS system bash). No bash-4-only features
# so this works on stock macOS too.
#
# Setup ($HOME/.zshrs/daemon.toml):
#     [http]
#     listen = "127.0.0.1:7733"
#     # Optional — required if listening on a non-loopback interface:
#     # [http.tokens]
#     # mybox = "long-random-secret"
#
# Override the default base URL or token via env:
#     export DAEMON_URL=http://127.0.0.1:7733
#     export DAEMON_TOKEN=long-random-secret    # only if tokens configured
#
# All wrappers route through `curl -s -f --json` so JSON encoding,
# Authorization, and error propagation are handled once. Output is the
# daemon's raw JSON; pipe through `jq` for pretty-printing.

# Internal: invoke curl with the right auth/content headers. Branching
# on DAEMON_TOKEN here keeps quoting safe in BOTH bash and zsh — the
# previous `$(_daemon_auth_args)` splice trick word-split
# `Authorization: Bearer <tok>` into three URL args under bash's
# default IFS, which made every wrapper print a "Could not resolve
# host: Bearer" warning before the real curl call ran. Using two
# direct `-H` args dodges that entirely.
