Part of #325.

Native schedules now run PHP's schedule definitions as published Server 2.5.14 runs them. Before this change, native accepted only a narrow subset.

What changes

• Cron. schedule_cron.rs ports dragonmantank/cron-expression 3.6.0: validation, aliases, names, ranges, steps, lists, L, W, # and ?, the 1,000-step search limit, and PHP DateTime behaviour around daylight-saving changes.
• Zones. schedule_zones.rs reads zone names as new DateTimeZone() does: numeric offsets, PHP's 144 abbreviations, and IANA names in any case.
• Specifications. schedule_spec.rs computes the next fire time across several cron expressions and offset intervals, using PHP's DateInterval grammar.
• Schedules. Creation follows PHP's Laravel rules and messages. Describe, history, pause, resume, trigger and delete match PHP's response shapes.
  • Triggers support all six overlap policies, buffering, closing the other run, run quotas, jitter, memo and note.
  • The tick drains buffered actions before due schedules.
  • Schedules are namespace-scoped and start runs in their own namespace.

Deliberate differences

• Resuming an active schedule returns 409 schedule_not_paused; PHP returns an unhandled 500.
• When another native node has already fired an occurrence, the tick skips it silently instead of recording stale_occurrence.
• Plain JSON array input and search attributes are refused, as native start refuses them.
• Native uses newer IANA rules (2026e) than PHP's bundled 2026.1 data for six zones: Casablanca, El Aaiun, Edmonton, Inuvik, Vancouver and Winnipeg.
• Fixed offsets of 26 hours or more are refused. PHP accepts offsets up to 100 hours.

Evidence

• scripts/conformance/cron-oracle regenerates three corpora byte for byte from the frozen PHP image. Native matches all of them:
  • 1,200 cron cases;
  • 1,068 zone spellings;
  • 600 whole specifications.
• The new schedule-policies fixture sends 60 requests and compares every response with reviewed published-PHP output. It passed locally on published PHP, embedded and this branch's native build; native from main fails it.
• A PHP-on-PostgreSQL HTTP diff matched native on 72 responses. The only differences were the two refusals listed above.
• Local tests passed: the lib suite (154 tests), the SQLite execution suite (298 tests), the schedule and namespace tests on PostgreSQL, MySQL 8.4 and MariaDB 10.11, and all 176 contract unit tests.

Next: update, listing (visibility query and page tokens) and backfill; then narrowing the takeover schedule refusal (#568).

Cancelled this head's CI runs (39549600277, 39549600278) without results. #566 merged and left this branch in conflict on the port log, and the merge train updates one PR at a time. CI will run again when this branch is brought up to date in its turn.

[rmcdaniel]

Merged main after #566, #567, #568, #558 and #572 (f49568f). The takeover schedule check from #568 is narrowed in the merge to what native still cannot run. The Shared Server fixtures trigger path list now gives each new contract test its own entry: #570's original edit and #572 had each appended its test to an existing entry. Lib (156), schedule and signal tests pass locally, along with the 5,058 contract unit tests.
