Hook: hard fail on toolchain install errors

Replaced warn-and-continue pattern with set -euo pipefail and die().
If a toolchain install fails, the session cannot build — stop immediately.

# SessionStart hook — install the polyglot build toolchains for this repo.
#
# Claude Code on the web runs in an ephemeral container: anything installed
# outside the cached project tree vanishes on restart. This hook reinstalls the
# toolchains the project depends on at the start of every session:
# * GNAT + gprbuild + GnuCOBOL (apt: gnat gprbuild gnucobol)
# * Pony (ponyc) via ponyup
# * Alire (alr) 2.1.1 (prebuilt release zip)
# toolchains the project depends on at the start of every session.
#
# Design rules:
# * IDEMPOTENT — each tool is skipped if it is already on PATH (command -v).
# * NON-FATAL — a failed download/install must NOT break the session. We never
# run `set -e`; every step is guarded and the script always exits 0.
# * Warnings (not errors) are logged so failures are visible in the session log.
# * HARD FAIL — if an install fails, the session cannot build. Stop.
