Switch to Nextcloud-major-aligned versioning starting at 34.0.0

Leading version number now tracks the supported Nextcloud major
(currently 34, i.e. Hub 26 Spring) instead of an independent 0.x
count, so compatibility is visible at a glance. Documents the scheme
in CLAUDE.md's release process section.

 ### Release process
 
+**Versioning scheme (from 34.0.0 on): `<nextcloud-major>.<minor>.<patch>`.** The leading number tracks the minimum/maximum Nextcloud major version declared in `appinfo/info.xml`'s `<dependencies><nextcloud .../>` (currently `min-version="34" max-version="34"`), not this app's own feature history - so it only changes when the supported Nextcloud major changes (e.g. dropping/adding NC 34 support bumps to `35.0.0`), and resets `minor`/`patch` to `0.0` at that point. Ordinary fixes/features within the same supported NC major bump `minor`/`patch` as usual (semver-ish, without a leading `0.`). Versions before `34.0.0` (`0.1.x`/`0.2.x`) predate this scheme.
+
 1. Bump `<version>` in `appinfo/info.xml` and `version` in `package.json` (keep them in sync).
 2. Commit, push to `main`, confirm the run of `.gitea/workflows/build-main.yml` is green.
 3. `git tag vX.Y.Z && git push origin vX.Y.Z` — this triggers the tag branch of the same workflow, which re-runs the checks, builds the frontend, runs `make appstore`, and attaches `workflow_deck_automation.tar.gz` as the asset on a normal (non-pre-) release for that tag.
