chore(release): build 02.60.00 [skip ci]

docs(ajax): correct preupdateAck docblock to one-shot skip semantics

The docblock still described the removed 10-minute throttle ("arms BOTH
keys"). It now sets a one-shot, action-keyed skip flag consumed once by
the system plugin. Comment-only; no behaviour change.

 ## [02.59.00] --- 2026-07-12
 
 ### Fixed
+- Pre-update backup now fires for **every** extension update/uninstall, not just the first one in a 10-minute window. A coarse 600-second session throttle (armed after any pre-action backup — even after updating MokoSuiteBackup itself or a core Joomla update) was disabling the client-side interceptor **and** the server-side fallback for *all* extensions for 10 minutes, so distinct updates silently went un-backed-up (looked like "only the backup extension triggers it"). Replaced with **one backup per Update action**: a single batch/click still backs up once (deduped per-request), the client re-fire is skipped via a **one-shot** action-keyed flag (consumed once), and the core-update path uses its own dedicated key so it no longer suppresses extension backups.
 - Pre-update backup on the **Joomla Update** page is now **seamless** (Akeeba-style): after the full-screen backup runs, the plugin auto-ticks Joomla's "I have taken a backup" checkbox and clicks Install, so the update continues automatically instead of stopping for a second manual click.
 - Pre-update full-screen backup now actually fires on the **Joomla Update** page. The "Install the update" button posts to `option=com_joomlaupdate&layout=update` (Joomla's confirm/updating page) — carrying **only `layout=update`**, no `view`/`task` — so the previous match on `view=update`/`update.install` never triggered. The plugin now intercepts `layout=update` (as well as `view=update` and the legacy `update.install`) and returns the browser there flagged `is_backed_up=1`.
 
 ### Added
 - **Snapshot transfer + master→slave injection (#237):** download a content snapshot as a portable **`.msbsnap`** file (zip of `manifest.json` + `snapshot.json` + a sha256 integrity check); **import** one on another site via a new Import button on the Snapshots page (materialises a local snapshot record you can then restore); and a **direct injection API** — `POST /api/index.php/v1/mokosuitebackup/snapshot/inject` — so a **master** site can push a snapshot straight into a **slave**'s Web Services API. Two conflict modes ship now: **overwrite** (replace matching items by ID — master wins) and **create** (skip existing, add only new), selectable per inject call or defaulted in **Options → Snapshot Transfer**. A receiving site must opt in via the new *Allow Snapshot Injection* setting. A third **duplicate** mode inserts everything as brand-new records with **remapped IDs** (articles, categories, modules — plus their tags, custom-field values and featured flags) using Joomla's Table API so assets/UCM/nested-sets stay valid; each item is inserted defensively (a bad item is skipped and logged, never fatal).
-- Full-screen backup now also fronts **extension updates and uninstalls** (Extensions → Update / Manage), not just core Joomla updates. Because `com_installer`'s `update.update` / `manage.remove` are POST actions (CSRF token + a checked `cid[]` list) that a server-side redirect can't cleanly resume, this is done client-side: the toolbar Update/Uninstall click is intercepted, the selection is captured, the full-screen backup runs, and on return the original selection is restored and the real POST form is re-submitted. Gated by `backup_before_update` / `backup_before_uninstall`, super-user only, and skipped if a backup already ran this session.

Gated by `backup_before_update` / `backup_before_uninstall`, super-user only, and deduped to one backup per Update action.
 - Manual **"Backup Now"** completion now offers a **View backup record** button (links straight to the record that was just created). It appears only for manual backups — the pre-update / pre-uninstall flow hands control back to Joomla instead.
 - **Full-screen backup screen** (`view=runbackup`) for both pre-update and manual backups, modelled on Akeeba's Backup-on-Update — replaces the earlier popup-modal approach. Clicking Joomla's **Install the update** now redirects (server-side, Akeeba-style) to a dedicated full-page backup screen that runs the stepped backup with a real progress bar and then **automatically continues the update** via a validated `returnurl` (flagged `is_backed_up=1` so the backup isn't repeated). Crucially, **no backup runs synchronously inside the update request** — which is what white-screened large sites. The dashboard **Backup Now** now opens the same full-screen screen instead of an inline modal. (#196)
 - Retention now prunes **remote** copies too: when a backup is pruned by age/count, its archive is deleted from every enabled remote destination (SFTP / FTP / S3 / Google Drive), not just the local copy. Each uploader gained an idempotent `delete()` method (already-absent file = success), and removal is best-effort — a failing destination is logged but never blocks local pruning. The shared standalone `restore.php` is intentionally left in place (every backup overwrites it, so newer backups still depend on it). (#229)

 ### Fixed
 - Package `postflight` now removes the orphaned `com_component-mokosuitebackup` registration (stray extension record, admin menu items, schema rows, and `administrator/` folder) left behind by the old "Type - Name" component `<name>` — self-healing on update so affected sites reconcile to the real `com_mokosuitebackup`.

-### Fixed
-- Component manifest `<name>` reverted to the element-safe `MokoSuiteBackup`. The "Type - Name" convention derived element `com_component-mokosuitebackup`, registering a duplicate component and leaving the real `com_mokosuitebackup` orphaned on the old version. (#213)
