Safari web clipper (macOS, Mac App Store)

Safari Web Clipper (macOS → Mac App Store)

Adds a Safari Web Extension target for the existing web clipper. Reuses the WXT bundle unchanged; the only product code change is allowing Safari's extension-origin scheme on the desktop capture server.

Spec: docs/superpowers/specs/2026-07-01-safari-web-clipper-design.md
Plan: docs/superpowers/plans/2026-07-01-safari-web-clipper.md

Done (code)

• Task 1 — safari-web-extension:// added to the capture-server origin allowlist (EXTENSION_ORIGIN_PREFIXES, single source of truth). New isExtensionOrigin tests (Safari/Chrome/Firefox accept, web-origin/undefined reject). 26 main tests pass.
• Task 2 — WXT Safari MV3 build scripts (dev:safari/build:safari/zip:safari). build:safari verified: .output/safari-mv3/manifest.json is MV3, no WXT warnings, all five risky manifest keys pass through. README build section added.

Remaining (macOS-only, draft until done)

• Task 3 — safari-web-extension-packager → committed Xcode container app (com.memrynote.web-clipper) + com.apple.security.network.client entitlement (required for loopback under App Sandbox).
• Task 4 — Acceptance gate: confirm the background fetch attaches Origin: safari-web-extension://<UUID> and reaches loopback under the sandbox. Go/no-go.
• Task 5 — Code-sign, notarize, App Store Connect listing ("Data Not Collected"), submit; README install flow + release runbook.

Notes

• Branched off origin/main, which does not include the uncommitted :firefox/:edge script edits in the working tree — reconcile script placement at merge.
• Docs gate skipped (MEMRY_DOCS_IMPACT_SKIP=1): the allowlist line is an inert precursor; user-facing Safari docs land with Task 5 when the extension is actually installable.
