test(performance): add the J1 launch-to-usable journey benchmark (#1698)
* test(performance): add the J1 launch-to-usable journey benchmark Implements plan items A1, A3 (J1 only) and the minimal A4 from .plans/2026-09-25-performance-journeys-ratchet.md. - journey-renderer-probe.ts: init-script probe counting DOM mutations, layout shifts and long tasks until the first source card is visible on /workspace with the splash removed; unit-tested with jsdom fixtures. - journey-main-ipc-capture.ts: counts bridge invocations from the preload's renderer-API trace channel up to a sentinel call the probe fires, so the IPC counter is exact without touching production code. - launch.journey.ts + playwright.journeys.config.ts: seeded profile (one M3U source, one Xtream portal on the loopback mock), one warm-up and five measured iterations, fresh process and data directory each, writing dist/performance/journeys/<timestamp>/summary.json with exact counters and P50/P90 wall-clock. - Nx target electron-backend-e2e:journeys and root script perf:journeys. - docs/architecture/performance-journeys.md, README, context and validation map entries. renderer.cdTicksToFirstCard and main.sqlStatementsBeforeReadyToShow are reported as unavailable with the reason instead of being faked. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(performance): gate the renderer load so the probes never race startup Review follow-up for #1698. - journey-renderer-gate.cjs: a main-process hook loaded with `-r` (the mechanism Playwright uses for its own loader) makes the first loadFile/loadURL navigate to about:blank and holds the real load until the test releases it. Playwright reports no page before a navigation commits, so this is what lets the renderer probe be registered on the page before the real document exists; the IPC capture is installed before the release too. A safety timeout releases the gate on its own and marks the iteration invalid. Unit-tested with a fake BrowserWindow. - launch-journey-app.ts: registers the probe on the parked page, releases the gate, waits for the real document to commit, fails fast when the probe is missing, and refuses an iteration whose gate timed out, saw a second load, or released before the probe was in place. - journey-renderer-probe.ts: entries delivered live after the terminal batch are buffered and filtered by the same cutoff as queued ones, and the cutoff is sampled in a timer queued from the first rAF, i.e. after the card's frame is painted, so the render task's long task and layout shift are consistently included. - launch-journey-record.ts: layoutShiftScore rounded to three decimals; a 0.0001 shift flipped in and out of the cutoff between iterations. - playwright.journeys.config.ts: reuse a mock server left on the journeys port locally (its fixtures are deterministic); CI still starts its own. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(performance): validate the journey gate after the probe completes Codex follow-up on #1698: the gate state returned by release() cannot see a reload or recovery navigation that happens before the first card. Re-read the live state once the renderer probe has finished and validate that instead, so an iteration spanning an extra navigation is rejected. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(performance): fail an iteration whose performance observers were unavailable Codex follow-up on #1698: a renderer that cannot observe layout-shift or longtask entries used to pass the probe with zero counters, which a ratchet could not tell apart from a genuine zero. The probe assertion now rejects such an iteration and names the missing observer.

chore(performance): measure initial bytes of the built web app (#1692)
First step of the performance-journeys ratchet (plan thread: J1 `launch`, counter `renderer.initialBytes`).
- `tools/performance/measure-initial-bytes.mjs` reads the built `dist/apps/web/index.html` and sums `index.html` plus every same-origin `<script src>`, `<link rel="stylesheet">` and `<link rel="modulepreload">` it references. Manifest, icons, external URLs and lazy chunks are not counted. A referenced file missing from the build fails the measurement instead of counting as zero bytes.
- `--json` prints the breakdown; `--summary <file>` writes the `journeys.<journey>.counters` shape a ratchet checker will consume (next PR).
- New Nx project `performance-tools` (test + lint targets), Tier B in `tools/coverage/coverage-policy.json`, root scripts `perf:initial-bytes` and `perf:tools:test`.
- New contract `docs/architecture/performance-journeys.md`, linked from the validation map, the agent context map and the README.
- **Review follow-ups:** resources are deduplicated by request URL (query kept, fragment dropped); `index.html` is parsed with parse5 (already a repository dependency, scripting enabled), so comments, bogus comments, raw-text bodies (script/style/noscript/title/textarea), inert `<template>` contents and character references in attributes all follow the HTML5 algorithm instead of a hand-written scanner; the review's edge cases stay as regression tests; docs show the `pnpm --silent` form for JSON output and explain how the counter relates to Angular's rounded "Initial total".
- **Found while measuring:** the environment files and the playback diagnostic panel imported the whole `package.json` (`import packageJson from '@package'`), which esbuild cannot tree-shake, so `main.js` carried the complete file and the counter moved with every script or dependency edit. They now import `{ version }` only (
