Prepare v1.74.0

Seven version sources move together to 1.74.0; both changelogs gain the
stable section aggregated from the previous stable v1.73.0, the release
notes carry three itemised bullets on each side plus the grouped
small-fixes bullet, and STATUS says what this release is.

What the user gets since v1.73.0: the plan is noticeably smoother and in
Firefox dramatically so — a pan frame now moves what is already drawn by
a composited transform with the scene re-rasterizing on a budget (#531),
and a marker shadow sized in container units no longer restarts a
non-composited animation on every marker at once (#524); the printed plan
is about a third larger, because the in-plan dimension labels shrank and
the separate column of external dimensions is gone (#530); a plan left
over from the era of rooms without walls can be edited again, the
leftover cleaned up on the first save instead of refusing every change
(#529, reported in #527). Grouped under small fixes: alignment guides
follow the gesture again (#521), the summary panel neither freezes the
first frame nor claims an unavailable source (#509) and its settings
dialog scrolls again (#508), a space switch no longer replays a
neighbouring door's leaf (#525), and the card downloads 12.8 KB less on a
cold start (#526).

The speed verdict for #531 is deliberately not claimed here: headless
Firefox and Chromium hold 60 fps on both the old and the new path, so it
is owed by a profile from the owner's machine on the same pan.

`npm test` 2528/0/1 skip, `pytest tests_backend` 467 passed, release

-| Current local cycle | v1.74.0-beta.3 continues the line after the stable v1.73.0. User-visible in this beta: dragging the plan is smooth again — a gesture frame now moves what is already drawn by a composited transform and the scene re-rasterizes on a budget (100 ms, or a 15 % shift) instead of on every frame, which on the owner’s 144 Hz Firefox cost 200 ms per frame with the refresh driver skipping 124-144 ticks a second waiting for paint (#531); and the printed plan is about a third larger, because the in-plan dimension labels shrank by a quarter and the separate column of external dimensions is gone, so the drawing keeps a whole scale step (#530). Everything from v1.74.0-beta.2 stays in the line: #529, #524, #525, #526, plus internal #528 and #518. The speed verdict for #531 is deliberately NOT claimed by the sandbox — headless Firefox and Chromium hold 60 fps on both the old and the new path; it is owed by a Firefox profile from the owner’s machine on the same pan. Publication requires green Validate on the exact candidate SHA; `main` stays at v1.73.0. |

 | Hidden Alpha Stage | #89 Stage 1 ships in v1.63.0-beta.1, #122 Stage 2 in v1.64.0 and #160 Stage 3 in v1.73.0-beta.1. The same hidden `iso` view uses the fixed 4° camera, raised/tethered device-room-lock overlays, deeper openings and bounded theme materials; #471 removes the overlay plates from paint while retaining their safety geometry. Since #448 the experiment is enabled only through the single indefinite browser-local `hp_alpha` gate; it is not expiring and has no per-stage key. Flat remains default; editors, `houseplan-space-card`, floor effects, stored coordinates and HA actions remain unchanged. Stage 3 stays internal and is absent from public changelog/user documentation. |
 | Workflow | Superseded 2026-08-12: the pre-1.62 rule of "local edits without tests or commits" is **dead** — since release 1.62 every product change follows `PROCESS.md` (issue in `S5-ready`+, branch `issue/<NN>-slug`, trailers on every commit, review pipeline; `AGENTS.md` is the summary). Release mechanics below remain current. A requested pre-release gets a production build plus the smallest targeted unit/smoke set covering the changed surfaces, one tested `dev` commit/tag and a GitHub Release with `prerelease=true`; `main` stays untouched. The complete local frontend/backend/smoke gate runs only before a stable release, after which `main` is fast-forwarded to the exact tested `dev` SHA and the GitHub Release uses `prerelease=false`. Release bodies are short and bilingual (Russian first); every bullet links its GitHub issue (#NN) so the #328 rules stay machine-checkable. A STABLE body aggregates the changelog since the PREVIOUS STABLE release (never since the last beta): features/fixes described across the line's beta changelogs must appear, while bugs that were introduced and fixed strictly inside the beta line (never shipped in any stable) are excluded — draft with `npm run release:notes -- <tag>`, curate by hand, then `npm run release:notes -- <tag> --verify` must pass. `Мелкие исправления и улучшения` / `Small fixes and improvements` is allowed only when the range really contains user-visible work not itemised in the body; a single-issue hotfix ships without it (the verifier enforces this). Every body ends with separate links to the Russian and English changelogs. Open or partially delivered issues are never presented as shipped. Telegram announcements are sent only for stable releases; beta and RC publication is silent. `docs/RELEASE-NOTES.md` is the current canonical body instance; `npm run release:prerelease -- <tag> --issues=… --yes` is the primary local publication path and the manual `Publish prerelease` workflow is its GitHub-only equivalent once present on `main`. Nothing is copied to the home instance by hand |
 | GitHub | https://github.com/Matysh/houseplan-card — [Issues](https://github.com/Matysh/houseplan-card/issues) are the canonical task records; their labels carry priority and workflow status (`PROCESS.md` §9). GitHub Projects is no longer used. `main` carries stable releases; pre-release tags may point directly at `dev`. Work lands on `dev` and is merged into `main` for a stable release, so `dev` is normally equal to or ahead of `main`, never behind.
