holocron 0.2.0

# Kitchen-sink: this file contains MULTIPLE errors of different kinds.
#
# ⚠️ Current limitation: the compiler bails on the FIRST error and exits.
# So a single run will only surface one of the issues below — fix it,
# re-run, the next one shows up, repeat. "Collect all errors" is a planned
# improvement (CLAUDE.md HOLO-DIAGNOSTICS).
#
# Errors in this file:
#   1. line 20 — duplicate enum type `status`
#   2. line 28 — unknown column type `not_a_type`
#   3. line 35 — duplicate relation `tasks`
#   4. line 42 — view sources an unknown table (`ghost`)
#   5. line 50 — view selects an unknown alias (`x`)
#
# Run: cargo run -- samples/error_multiple.yml
#
# Tip: comment out the higher-line errors as you fix them to see the
# lower ones surface, until the file compiles cleanly.
