peptiderepo d69f637b06 refactor: extract upgrade logic to PSA_Upgrade class (fixes CI)
CI on 61cf00c failed PHPUnit with "Call to undefined function
plugin_dir_path()" — the test required peptide-search-ai.php, which calls
plugin_dir_path() at top level (line 19) before any hook. Stubbing every
top-level WP function the plugin file touches was the wrong shape of fix.

Proper fix: move the upgrade logic into includes/class-psa-upgrade.php so
the test can require just the helper class, matching the pattern every
other includes/ module follows.

- New: includes/class-psa-upgrade.php with PSA_Upgrade::is_needed()
  (pure) and PSA_Upgrade::maybe_run() (driver). OPTION_NAME and
  DEFAULT_STORED_VERSION exposed as constants.
- peptide-search-ai.php: psa_admin_init() now calls PSA_Upgrade::maybe_run();
  the inline helper functions and docblocks are removed.
- tests/bootstrap.php: loads class-psa-upgrade.php alongside the other
  tested classes.
- tests/unit/UpgradeTest.php: rewritten against PSA_Upgrade; adds two
  extra assertions on the constants for stability.
- ARCHITECTURE.md: refreshed to reference the class and its constants.

No behavioral change. The cost-tracker schema upgrade still runs once per
admin_init when PSA_VERSION advances past psa_db_version.
