clad2 baa683211e fix(labels): pass bootstrap through the workflow_call boundary it was lost at
A called workflow cannot read the caller's dispatch inputs on this forge:
github.event.inputs is empty inside workflow_call even though the top-level
caller receives the value in both contexts (probe runs 6/7). The sweep's gate
read exactly that, so every dispatch-woken sweep bootstrapped — runs 459 and
523, ~20 label upserts per board event — while the trigger honestly logged
bootstrap=no.

The bridge, per the #6361 contract: labels-sweep.yml declares
workflow_call.inputs.bootstrap (string, default "no"); the dogfood caller and
the published CONSUMERS.md stub pass it via with.bootstrap with empty mapped
to "no" at the caller — kimi's edge: on schedule the top-level context is
empty, and an empty that slipped through would have turned every cron into a
bootstrap. The gate feeds the declared input to labels-reconcile unchanged,
so an invalid value meets the action's own yes|no refusal.

test/labels-bootstrap.test.sh pins every hop: the declared boundary, both
gates as the identity, no expression reading github.event.inputs (scoped to
${{ }} bodies — the file's prose names the context to explain it), the two
pass-throughs byte-exact, and the four value paths driven through the shipped
expressions into the action's real validator. Mutations: dropping the
declaration reds 4, dropping the pass-through reds 3, restoring the old gate
reds 2.

### Fixed
- The sweep's `bootstrap` value crosses the `workflow_call` boundary as a
declared input passed by the caller — a called workflow cannot read the
caller's dispatch inputs on this forge (#215).
- Before the bridge, `github.event.inputs` was empty inside the called
workflow, so every dispatch-woken sweep bootstrapped: ~20 label upserts on
each board event (#215).
- The caller maps an empty top-level value to `no` explicitly, so a
cron-woken sweep can never bootstrap; the declared input also defaults to
`no`, so a consumer that passes nothing gets the safe path (#215).
- The gate feeds the declared input to `labels-reconcile` unchanged, so an
invalid value meets the action's own `yes|no` refusal instead of being
silently coerced (#215).
- `docs/CONSUMERS.md`'s published sweep stub carries the same pass-through —
without it every consumer inherits the defect ceremony fixed for
itself (#215).
### Added
- `test/labels-bootstrap.test.sh` pins the bridge at every hop: the declared
boundary, both gate sites as the identity, no expression reading
`github.event.inputs`, the caller and stub pass-throughs byte-exact, and
the four value paths driven through the shipped expressions into the
action's real validator (#215).
