enhance(#3777): opt-in concurrent per-plan planners in chunked mode (#4346)

* test(#3777): add failing-first coverage for concurrent per-plan planner dispatch

Extracts and executes the real bash blocks this PR is about to add to
plan-phase.md and chunked-planning-mode.md (CHUNKED_PARALLEL resolution and
the BATCH_PLAN_IDS dedup guard), plus config-set/config-get coverage for the
new planning.chunked_parallel key. Expected RED against the current shipped
workflow text — the extraction anchors do not exist yet.

* feat(#3777): dispatch chunked mode's per-plan planners concurrently within a Wave

Adds opt-in planning.chunked_parallel (default false, byte-identical to the
existing serial loop). When true and the runtime's negotiated dispatch
capacity (dispatch-capacity, #3673) is greater than 1, chunked planning's
per-plan Tasks that share one outline Wave are issued together instead of
one at a time; a later Wave still waits for the current one to be verified
on disk and committed. A host with no declared maxConcurrency (most
non-Claude runtimes today) stays serial regardless of the setting.

Resolution and the Plan-ID dedup guard live in chunked-planning-mode.md
itself (gated on the section's own CHUNKED_MODE skip-check) rather than in
plan-phase.md, so a non-chunked run pays no extra gsd_run calls.

* test(#3777): repoint extraction at chunked-planning-mode.md after the move

CHUNKED_PARALLEL resolution moved out of plan-phase.md into
chunked-planning-mode.md itself (see the preceding commit); update the
test's extraction path and header comment to match.

* fix(#3777): relocate the canonical runtime-launcher preamble before its first use

The CHUNKED_PARALLEL resolution block's two gsd_run calls landed earlier in
the file than the sole existing preamble (in the commit step), which
tests/runtime-launcher-parity.test.cjs's (B) check requires to precede every
gsd_run call in the file. Move the preamble (not duplicate it) to the top of
the resolution block; the commit step's fenced block now just calls
gsd_run directly.

Caught by the GREEN checkpoint gsd-test run before push.

* fix(#3777): strip the canonical preamble from the extracted resolution block

The CHUNKED_PARALLEL resolution fence now carries the relocated
runtime-launcher preamble as its first line (previous commit). Extracting
the whole fence and running it after the test's own gsd_run stub let the
embedded preamble's own resolver logic `unset -f gsd_run` and exit 1 before
reaching the resolution logic, since no real gsd-tools.cjs exists in the
temp script dir — every test calling runChunkedParallelResolution() failed.

Strip the preamble (sourced from gsd-core/workflows/_runtime-launcher.snippet.sh,
the same file scripts/sync-runtime-launcher.cjs treats as canonical) before
splicing in the stub, so this suite tests only the resolution logic it is
actually about.

Caught by the post-rebase gsd-test run before push.

* docs(#3777): add the How-To page the phase gate requires

Enablement is 2 commands (config-set, then --chunked), which this repo's
own doc-quadrant gate flags as how-to-owed: a reference table cannot carry
a sequence. Covers enablement, the dispatch-capacity gate's honest
"most runtimes today: no effect" case, and the two accepted trade-offs.

An earlier reasoning pass (recorded in .gsd/phase/.../70-docs.json before
this commit) had incorrectly claimed #3034 shipped with no equivalent
how-to page, as precedent for skipping one here. That claim was false —
docs/how-to/enable-parallel-reviewer-lanes.md exists and is indexed. The
phase gate caught the omission before merge; corrected here.
