feat(macos): persist Psyche-owned Coven sessions

[BunsDev]

Summary

• mark Psyche-launched Coven Code sessions with the exact source:psyche-build provenance label
• show only active Psyche-owned sessions, deduplicate overlapping native and daemon rows, and focus the existing physical attach pane
• preserve sessions across packaged app restarts without creating duplicate attach processes
• add a parser regression test and repair the pre-existing malformed browser shortcut handler found during packaged acceptance

Verification

• pnpm exec vitest --run --minWorkers=1 --maxWorkers=1: 2146 passed, 11 skipped
• pnpm typecheck
• cargo fmt --check
• cargo check
• cargo test: 115 passed
• pnpm smoke
• pnpm smoke:pack
• node --check native/macos/psyche-build-tauri/web/main.js
• git diff --check
• clean packaged restart/rehydration acceptance: exact session 5d6ab4c0-4bcd-4925-80f3-9fc353b9f097 and source label survived restart; one daemon row and one native attach process; no historical completed rows
• packaged DMG SHA256: 7f61dd6c20048ce45ea2b51ca94e1485cdc68b7adc4dad944558bd0782be5a77

Pull request overview

This PR updates the macOS Tauri Psyche Build app to treat Coven daemon sessions as Psyche-owned only when they carry the exact provenance label source:psyche-build, to render only active eligible sessions, and to persist/reuse attachments safely across app restarts while preventing duplicated rows and accidental relabeling.

Changes:

• Introduces an explicit “Psyche-owned active” predicate for Coven sessions (label + live status), and applies it to grouping and search filtering.
• Deduplicates overlapping daemon session rows across saved projects by deterministically assigning each eligible session ID to exactly one project section.
• Wires provenance through native coven chat launches (env contract), scrubs it for coven attach, and adds regression/contract tests + updated docs/smoke guidance.

native/macos/psyche-build-tauri/src-tauri/src/lib.rs	Enforces launch env contract for coven-chat, forbids env for coven-attach, and centralizes env application (including removing provenance for attach).
native/macos/psyche-build-tauri/src-tauri/src/coven_sessions.rs	Normalizes/validates daemon labels into a bounded safe list; adds tests for missing/malformed labels behavior.
docs/superpowers/specs/2026-08-08-psyche-owned-active-coven-sessions-design.md	Documents overlap ownership rules and updated rail rendering pipeline.
docs/superpowers/plans/2026-08-09-deduplicate-overlapping-coven-session-rows.md	Adds implementation plan documenting the overlap dedupe approach and verification steps.
docs/SMOKE.md	Updates packaged smoke steps to validate provenance labels, visibility rules, and non-relabeling attachment behavior.
docs/COVEN-SESSIONS.md	Updates macOS rail behavior documentation to reflect the new provenance + active-only visibility contract.
tests/tauriWebBundles.test.ts	Adds a regression gate to node --check the committed main.js before packaging.
tests/tauriSessionModel.test.ts	Updates/extends model coverage for Psyche-owned active filtering and “search cannot reveal hidden sessions”.
tests/tauriFooterStatusBar.test.ts	Updates expectations around the new covenSessionAssignments seam in main.js.
tests/tauriCovenSessionSiderail.test.ts	Adds overlap dedupe behavioral tests and ensures only eligible sessions render.
tests/tauriCovenSessionNativeContract.test.ts	Adds a contract test ensuring provenance wiring and attach scrubbing across JS↔Rust seams.
tests/tauriCovenSessionLifecycle.test.ts	Updates compiled dependencies; adds lifecycle coverage for re-creating attachments after exit.
tests/tauriCovenLaunch.test.ts	Verifies coven-chat sets provenance env and coven-attach does not pass/serialize it.
