HQ_ROOT not exported in core/scripts/run-project.sh (sibling of #12) — prd.json false-negative

[spencerrwise]

Bug

core/scripts/run-project.sh computes HQ_ROOT at the correct depth
(${SCRIPT_DIR}/../..) but does not export it. Line 78 does
exec bash "$TARGET"; the target .claude/scripts/run-project.sh then
re-derives HQ_ROOT from its own BASH_SOURCE via its overridable
default HQ_ROOT="${HQ_ROOT:-$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)}".
From .claude/scripts/, that is <root>/.claude — one level too shallow.
With no exported HQ_ROOT, the default wins and resolves wrong.

Symptom

bash scripts/run-project.sh --dry-run <project> →
ERROR: prd.json not found for '<project>'. even though a valid PRD
exists, because resolve_prd_path() globs
"$HQ_ROOT"/companies/*/projects/<project>/prd.json. Only works when the
caller already has HQ_ROOT exported (masks it in interactive sessions;
breaks cold/headless callers). Verified on a real 9-story headless build:
failed at preflight until launched with HQ_ROOT="$PWD".

Relationship to #12

Sibling, not duplicate. #12 fixed the $(dirname)/.. depth in
audit-log.sh / compute-checksums.sh after the core/ consolidation.
Here the depth is already correct; the failure mode is propagation
(value right, not exported across exec). #12 said the consolidation
"missed siblings — this PR finishes the migration"; this finishes it for
run-project.sh.

Fix (one line, mechanical)

-HQ_ROOT="$(cd "${SCRIPT_DIR}/../.." && pwd)"
+export HQ_ROOT="$(cd "${SCRIPT_DIR}/../.." && pwd)"

Follow-up: the wrapper-only fix is insufficient in practice. The /run-project skill invokes the target .claude/scripts/run-project.sh directly, bypassing core/scripts/run-project.sh. The target's own ${HQ_ROOT:-$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)} default resolves to <root>/.claude (one level short) on a cold direct invocation. Complete fix needs the target's fallback depth corrected too: dirname/.. → dirname/../.. (keeping ${HQ_ROOT:-...} so an explicit export still wins). Verified across target-direct / wrapper / deep-subdir / explicit-override entry paths.
