feat(security): receipt admin scripts + user git-ops (zero exceptions)
Wire the remaining shell egress through gstack-egress-lib.sh:

- gstack-gbrain-mcp-verify: both JSON-RPC probe POSTs (initialize +
  tools/list) receipted fail-closed via payload files (hash == wire
  bytes). A refused receipt lands in the NETWORK class — no send.
- gstack-security-dashboard / gstack-community-dashboard: the
  community-pulse GETs receipted fail-open (read-only stats must not
  break over an audit hiccup).
- gstack-gbrain-supabase-provision: api_call receipted fail-closed.
  Each retry attempt hands the helper a fresh copy of the body file
  (the helper consumes its payload). The receipt hashes the request
  body only — the PAT never reaches the ledger or any log. Refusal
  exits 8 without retrying.
- git-class sha256:null receipts, fail-open: gstack-artifacts-init
  (ls-remote, initial push, fetch/pull recovery, retry push),
  gstack-brain-restore (staging clone, existing-repo fetch),
  gstack-session-update (self-update pull).

gstack-team-init needs no wiring: every git clone in it is inside an
echoed instruction string, not an executed command.

The lib now self-locates with shell builtins only (no dirname), so
sourcing works under the whitelist-PATH test harnesses.

feat(security): shared shell receipt helpers
bin/gstack-egress-lib.sh (sourced library, gstack-gbrain-lib.sh
precedent) provides _receipted_curl and _receipted_git: write the
egress receipt BEFORE the send via gstack-egress-receipt, hand curl the
SAME payload file via --data-binary @file so the receipt hash matches
the wire bytes exactly, then append a best-effort outcome. Per-call
fail policy: 'closed' refuses the send (return 3, problem/cause/fix
message on stderr) and 'open' warns and proceeds. Payload temp files
are consumed immediately per call — no EXIT traps, since callers like
gstack-telemetry-sync own their own EXIT trap and a sourced trap would
clobber it.

Tested end-to-end against a local Bun.serve listener: receipt sha256
equals the sha256 of the bytes the listener received, fail-closed
refusal never touches the network and carries the problem/cause/fix
stderr shape, fail-open warns and proceeds.
