Issue #290: File ▸ Open Recent lists the recent files (#323)

* Issue #290: File ▸ Open Recent lists the recent files

The Home view kept a recent-files list but the File menu had no way to
reach it; Acrobat shows File ▸ Open Recent and the request asked for
exactly the menu wiring.

A new command file.open_recent renders as a submenu of the live list
right under Open… (disabled while the list is empty); each entry opens
its file or focuses the tab already showing it, which is now shared
with the Home view's list through the new open_recent() instead of a
second copy of that check. The command palette runs it as "open the
most recent file", or says there are none. Translations added to every
catalog (Japanese, Czech, Spanish, both Chinese and Brazilian
Portuguese are test-covered).

Test: commands.rs::the_open_recent_menu_lists_files_and_opens_one
(submenu lists a seeded recent file and clicking it opens a new active
tab on that path) and commands.rs::the_open_recent_menu_is_disabled
while_the_list_is_empty. Both failed before the change (no such menu).

* Build: cap cargo jobs and lighten the dev profile

On a 7.1 GiB machine the default one-job-per-core (12) with every
dependency at opt-level 2 plus full debuginfo swap-thrashes the box
frozen mid-build. jobs = 4 bounds peak memory to a few GiB and matches
GitHub runners (4 vCPUs), so CI is unaffected; dependencies drop to
opt-level 1 with debug = false, which halves their build cost and
keeps them fast enough for a usable debug app. Own crates keep their
opt-level and full debuginfo.

Verified: a from-scratch rebuild of all dependencies peaked at ~2 GiB
used with the machine responsive throughout; the perf.rs frame-budget
tests still pass at the lower dependency optimization.

* Keep the build configuration as on main; French for Open Recent

The jobs and dependency opt-level changes are a separate build-policy decision.
French is coverage-checked since #291; catalog checksums refreshed.

* French for Open Recent again, and catalog checksums refreshed
