d1e9491fef feat(#2099): drive GitHub Copilot through the EoS descriptor + multi-event hook bus (ADR-1239)
Fold Copilot's residual runtime-literal branches onto descriptor-driven
hostBehaviors. Several issue premises were inaccurate (verified via research)
and deliberately NOT followed: writesSharedSettings/"legacy exclusion list"
(per-runtime descriptor data, copilot's false is correct); RUNTIME_CONTENT_DISPATCH.copilot
+ installSurface==='copilot-instructions' (already descriptor-driven);
extendedHookEvents (closed Claude/Gemini enum — hooks extended in code instead);
reapply ternary (already folded, kimi #2095).

Real folds (all byte-parity — golden byte-identical for every runtime):
- src/install-engine.cts + src/surface.cts: the two `.agent.md` filename cutovers
  (_copyStaged + _syncGsdDir) unified onto hostBehaviors.agentFileExtension via a
  new exported agentFileExtensionFor() accessor (kills the two-mechanism divergence).
- src/runtime-artifact-conversion.cts: applyAgentPathRewrites' copilot skip →
  hostBehaviors.noPathRewrite:true (antigravity #2096 precedent).
- bin/install.js uninstall: the two isCopilot cleanup branches → installSurface===
  'copilot-instructions' gate (symmetric with install-time).
- bin/install.js: `!isCopilot` in the two skipSharedHooksInstall checks →
  hostBehaviors.skipSharedHooksInstall:true (copilot has no shared gsd-*.js hooks).
- bin/install.js: three dead legacy inline-agent-loop isCopilot refs removed
  (copilot ∈ _DESCRIPTOR_AGENTS_RUNTIMES → unreachable; byte-parity proven by clean
  golden + real reachable-runtime install diffs). isCopilot dropped from 4 destructures.
Zero live `runtime==='copilot'`/`isCopilot` branches remain in bin/install.js,
install-engine.cts, surface.cts, or runtime-artifact-conversion.cts (AC2 guard scans all four).

UPGRADE 1 (multi-event hook bus): buildCopilotHookConfig() now emits preToolUse/
postToolUse/userPromptSubmitted/sessionEnd advisory handlers alongside sessionStart
(static inline bash/powershell — deterministic, golden-trackable). Only copilot.json's
gsd-session.json hash changes.

UPGRADE 2 (background dispatch): surfaced via the negotiated contract only —
dispatch.background:true exceeds the declarative-cli baseline and survives negotiation
with no downgrade warning. NO .agent.md frontmatter field (copilot has none). MCP
companion out of scope (AC4 names only 2 upgrades).

Tests: declarative-reference-copilot (adapter/axes/fail-closed + AC2 4-file source-grep
guard) + copilot-upgrades (live 5-event hook wiring; dispatch.background negotiation).
Matrix EoS note + how-to; changeset (Changed). capability-registry regenerated.

Incidental flaky-test RE-ARCHITECTURE (no-defer, maintainer-directed):
tests/opencode-review-reconstruction.property.test.cjs spawned ~600 synchronous
execFileSync('jq') subprocesses (numRuns:200 × 3 fast-check properties, one jq per
generated stream); a single jq freezing on a contended macos-22 CI runner hung the whole
unit-test chunk to its 600s kill (this PR's CI). --test-force-exit can't interrupt a
synchronous execFileSync, so the cure is to stop spawning per case, not just time-bound
it. Re-architected to run the SHIPPED jq program over the whole fast-check corpus in ONE
jq process: each generated stream is one compact-JSON array per line in a temp file,
`jq -c <PROGRAM>` (no -s) applies PROGRAM to each array (`.` == the array, exactly what
production's `jq -rs <file>` sees after slurping) and emits one result per line —
empirically byte-identical to the per-stream form across embedded-newline/empty/quote/
unicode/null-drop cases, and file-input (like production) so there's no stdin pipe to
deadlock on large I/O. ~600 spawns → 6; coverage unchanged (200-case corpus per property,
deterministic seeds) plus explicit boundary/diagnostic example batches. Still property-
tests the real shipped jq (no JS reimplementation). Per-call jq timeout retained as a
belt-and-suspenders bound.

23254ca5a7 fix(#1936): reconstruct OpenCode review from JSON events (#1992)
* fix(#1936): reconstruct OpenCode review from JSON events; diagnosable empty-output stub

On a large review prompt, OpenCode's default `build` agent runs a few read
tool calls then ends its turn with zero output tokens (reason:"stop",
output:0), so `opencode run --format default` emits empty stdout. The reviewer
block redirected stderr to /dev/null and wrote a generic "failed or returned
empty output" stub — so the phase silently lost its second independent reviewer
with no diagnostic and no timeout.

Rewrite the OpenCode reviewer block to invoke `--format json` as the primary
call and reconstruct the review from the assistant `text` parts (jq). Capture
stderr to a `.err` sidecar (mirrors the Codex block). When the agent emits no
text, surface the stop reason, output-token count, and stderr so the failure is
diagnosable. Gate the stub on the extracted CONTENT, not the output file size —
an empty jq extraction still prints a lone newline that a `[ -s file ]` check
would treat as populated. Document the wall-clock timeout as a Bash-tool param
(macOS lacks GNU timeout; opencode has no native timeout flag).

review.md was already at the DEFAULT size-tier ceiling (40956/40960), so the
fix cannot fit without reclassifying it into the LARGE tier (it is a
multi-reviewer orchestration file that outgrew "focused single-purpose"; 43.4 KB
sits well under the LARGE high-water mark). Recapture the 16 golden-install
fixtures — the diff is exactly one review.md hash per runtime. Regression block
folded into review-default-reviewers-workflow.test.cjs (new bug-NNNN test files
are not accepted).

* chore(#1936): add changeset

* test(#1936): property-test the OpenCode review jq reconstruction

Address the re-review's one actionable finding: the jq JSON-event → text
reconstruction had no fast-check property test.

Add tests/opencode-review-reconstruction.property.test.cjs. It extracts the two
shipped jq programs (OPENCODE_REVIEW, OPENCODE_DIAG) verbatim from
gsd-core/workflows/review.md and runs the real jq — not a reimplementation — so
the shipped logic is what gets tested. Properties: the reconstructed review
equals the newline-join of every assistant text part (order preserved); a stream
with no text part reconstructs to empty (drives the #1936 stub); null/absent text
parts are dropped, never rendered as "null". Plus example-based coverage of the
diagnostic edges the reviewer cited: missing .tokens.output and no step_finish
degrade to "?"; non-JSON stdout makes jq fail rather than masquerade as a review.

Verified the invariant has teeth (a comma-join jq fails the property).

* test(#1936): skip jq reconstruction property test when jq is absent

The property test shells out to `jq`, which GitHub's windows-latest runners do
not ship (macOS/Linux runners do). `execFileSync('jq')` therefore ENOENT-failed
the whole file on `test (windows-latest, *)`. Probe `jq --version` at load and
skip the suite when jq is not on PATH — the reconstruction logic is
platform-independent, so the assertions still run in full on every jq-present
runner (mirrors how golden-install-parity skips on win32).

Verified: jq present → 7 pass; jq removed from PATH → 7 skipped, 0 fail.

* test(#1936): skip jq reconstruction property test on Windows, not just when jq is absent

The prior guard skipped only when `jq` was absent from PATH — but the
windows-latest runners DO ship jq, so the suite still ran there and failed with
`jq: parse error: Invalid numeric literal` (confirmed from the CI job log). Root
cause is Node's child_process argument quoting mangling the jq program (it embeds
double quotes) on Windows, not the shipped review.md logic — the macOS/Linux legs
pass. Gate the suite on `process.platform === 'win32'` (still also skipping when
jq is absent), mirroring golden-install-parity's win32 skip. Logic is
platform-independent and fully asserted on every macOS/Linux CI leg.

Verified: macOS → 7 pass; simulated win32 → skips.
