merge: integrate origin/main (v0.18.3.0) — community wave

Resolves conflicts:
- VERSION: kept 0.19.0.0 (feature branch, higher than main's 0.18.3.0)
- package.json: kept 0.19.0.0
- CHANGELOG.md: preserved 0.19.0.0 at top, inserted 0.18.3.0 between 0.19.0.0 and 0.18.2.0

Main brought community wave (6 PRs + hardening):
- Windows cookie import
- Persistent browse server across CLI invocations
- One-command OpenCode install
- OpenClaw skill frontmatter fixes
- Cookie picker UI resilience

Auto-merge applied to design.ts, design-consultation/SKILL.md.tmpl,
design-shotgun/SKILL.md.tmpl, and plan-design-review/SKILL.md.tmpl —
main's UX_PRINCIPLES changes and my TASTE_PROFILE resolver coexist cleanly.

Regenerated all SKILL.md files via gen:skill-docs and refreshed ship
golden fixtures. 423 tests pass.

 - **`scripts/resolvers/preamble/`** — 18 single-purpose generators, 16-160 lines each. The composition root in `scripts/resolvers/preamble.ts` imports them and wires them into the tier-gated section list.
 - **Plan and reviews persisted.** Implementation followed `~/.claude/plans/declarative-riding-cook.md` which went through CEO review (SCOPE EXPANSION, 6 expansions accepted), DX review (POLISH, 5 gaps fixed), Eng review (4 architecture issues), and Codex review (11 brutal findings, all integrated and 2 prior decisions reversed).

+### Added
+- **Windows cookie import.** `/setup-browser-cookies` now works on Windows. Point it at Chrome, Edge, Brave, or Chromium, pick a profile, and gstack will pull your real browser cookies into the headless session. Handles AES-256-GCM (Chrome 80+), DPAPI key unwrap via PowerShell, and falls back to a headless CDP session for v20 App-Bound Encryption on Chrome 127+. Windows users can now do authenticated QA testing with `/qa` and `/design-review` for the first time.
+- **One-command OpenCode install.** `./setup --host opencode` now wires up gstack skills for OpenCode the same way it does for Claude Code and Codex. No more manual workaround.
+
+### Fixed
+- **No more permission prompts on every skill invocation.** Every `/browse`, `/qa`, `/qa-only`, `/design-review`, `/office-hours`, `/canary`, `/pair-agent`, `/benchmark`, `/land-and-deploy`, `/design-shotgun`, `/design-consultation`, `/design-html`, `/plan-design-review`, and `/open-gstack-browser` invocation used to trigger Claude Code's sandbox asking about "tilde in assignment value." Replaced bare `~/` with `"$HOME/..."` in the browse and design resolvers plus a handful of templates that still used the old pattern. Every skill runs silently now.
+- **Multi-step QA actually works.** The `$B` browse server was dying between Bash tool invocations — Claude Code's sandbox kills the parent shell when a command finishes, and the server took that as a cue to shut down. Now the server persists across calls, keeping your cookies, page state, and navigation intact. Run `$B goto`, then `$B fill`, then `$B click` in three separate Bash calls and it just works. A 30-minute idle timeout still handles eventual cleanup. `Ctrl+C` and `/stop` still do an immediate shutdown.
+- **Cookie picker stops stranding the UI.** If the launching CLI exited mid-import, the picker page would flash `Failed to fetch` because the server had shut down under it. The browse server now stays alive while any picker code or session is live.
+- **OpenClaw skills load cleanly in Codex.** The 4 hand-authored ClawHub skills (ceo-review, investigate, office-hours, retro) had frontmatter with unquoted colons and non-standard `version`/`metadata` fields that stricter parsers rejected. Now they load without errors on Codex CLI and render correctly on GitHub.
+
+### For contributors
+- Community wave lands 6 PRs: #993 (byliu-labs), #994 (joelgreen), #996 (voidborne-d), #864 (cathrynlavery), #982 (breakneo), #892 (msr-hickory).
+- SIGTERM handling is now mode-aware. In normal mode the server ignores SIGTERM so Claude Code's sandbox doesn't tear it down mid-session. In headed mode (`/open-gstack-browser`) and tunnel mode (`/pair-agent`) SIGTERM still triggers a clean shutdown — those modes skip idle cleanup, so without the mode gate orphan daemons would accumulate forever. Note that v0.18.1.0 also disables the parent-PID watchdog when `BROWSE_HEADED=1`, so headed mode is doubly protected. Inline comments document the resolution order.
+- Windows v20 App-Bound Encryption CDP fallback now logs the Chrome version on entry and has an inline comment documenting the debug-port security posture (127.0.0.1-only, random port in [9222, 9321] for collision avoidance, always killed in finally).
+- New regression test `test/openclaw-native-skills.test.ts` pins OpenClaw skill frontmatter to `name` + `description` only — catches version/metadata drift at PR time.
