* fix(execute-phase): honor gate="blocking-human" in auto-mode checkpoint handling
The package-legitimacy gate (#2827) spans two layers. gsd-executor refuses to
auto-approve a gate="blocking-human" checkpoint and escalates it so a human can
vet the package. execute-phase's checkpoint_handling step then dispatched purely
on checkpoint *type* and never read gate -- so under --auto/--chain it
auto-approved the checkpoint the executor had just refused to auto-approve.
Net effect: the slopsquatting defence was inert in exactly the unattended mode
where it matters. An [ASSUMED]/[SUS] package reached install with no human ever
seeing the prompt.
- gsd-core/workflows/execute-phase.md: carve out gate="blocking-human" (and the
package-legitimacy what-built markers) ahead of every auto-mode branch.
- gsd-core/references/checkpoints.md: document the gate attribute and its two
values. blocking-human previously appeared nowhere outside gsd-executor.md,
so no planner had a documented way to author a non-auto-approvable checkpoint.
- tests/package-legitimacy-gate.test.cjs: the existing regression test asserted
the executor half only, which is why it stayed green while the gate was open.
Now asserts the orchestrator half too.

* test(#2107): refresh golden-install-parity hashes for edited gsd-core files
The golden fixtures pin content hashes for gsd-core/references/checkpoints.md
and gsd-core/workflows/execute-phase.md, both edited by this fix. Regenerated
via UPDATE_GOLDEN=1; only those two keys change across all 17 runtime fixtures.

* fix(#2107): keep the carve-out inside the ADR-857 host-loop budget
The ADR-857 phase-6 ratchet pins execute-phase.md below 93600 LF bytes so
optional-feature logic keeps migrating out of the host loop. The carve-out
first landed 623 bytes over that ceiling.
Move the two-layer rationale (why gsd-executor escalates these checkpoints)
into references/checkpoints.md, where the gate is now documented, and reduce
the workflow to the operative rule. execute-phase.md is 93589 bytes, under
the ceiling; the gate token and both <what-built> marker strings are kept
because the orchestrator matches on them.
Refresh the two baselines the edit invalidates: golden-install-parity
fixtures (only the checkpoints.md and execute-phase.md hashes move) and
workflow-size-baseline.json (one line). The ADR-857 ceiling itself is
untouched.

* fix(#2107): executor honors blocking-human on the decision branch + gate transport
Review found the fix incomplete one layer down. Two executor-layer gaps:
1. Blocker — agents/gsd-executor.md auto-mode dispatch gated
checkpoint:human-verify on gate="blocking-human" but the checkpoint:decision
branch below auto-selected the first option with no gate check. The executor
resolves a decision itself (auto-selects and continues) without returning it,
so the orchestrator carve-out never runs for it. A planner following the new
checkpoints.md rule 6 ("gate a decision whose default would be wrong to
assume") would have it silently auto-selected under --auto/--chain — the exact
#2107 harm, one checkpoint type over. The decision branch now STOPs and
returns for an explicit human decision when gate="blocking-human".
2. Major (transport) — checkpoint_return_format carried no field conveying the
gate to the freshly-spawned orchestrator, so recognition of the proactive
pre-install checkpoint rested on freeform prose. Added a **Gate:** field to
the return format and re-pointed the execute-phase carve-out at it
("If the returned Gate: is blocking-human"). Net byte-negative: execute-phase.md
drops 93589 -> 93583, widening ADR-857 headroom from 11 to 17 bytes.

* test(#2107): cover decision carve-out + gate transport, de-vacuum conditional tests
- New: 'auto mode does not auto-select a blocking-human decision checkpoint'
asserts the executor decision branch STOPs on blocking-human. Verified red on
the pre-fix executor (2 fail), green with the fix (27 pass).
- New: 'checkpoint_return_format transports the gate ...' asserts the **Gate:**
field carries blocking-human across the executor->orchestrator boundary.
- New: 'auto-select rule for decision is conditional' — orchestrator-side mirror
of the human-verify conditional test, for the execute-phase decision branch.
- Fix vacuous test: both conditional tests now assert the anchor matched
(length > 0) before iterating, so anchor drift can no longer pass with zero
assertions.

* test(#2107): refresh golden + size baselines for executor + execute-phase edits
Regenerated via UPDATE_GOLDEN=1 and update-size-baseline.cjs. Only the
gsd-executor.md and gsd-core/workflows/execute-phase.md hashes move across the
runtime fixtures (35 ins / 35 del, no keys added or removed); checkpoints.md is
unchanged this round. Size baselines: gsd-executor.md 43607 -> 43973,
execute-phase.md 93589 -> 93583 (still under the ADR-857 ceiling).
