Add iran-pay 0.1.0 + parsitext 0.1.1 (tantivy, IBAN gen)

[r21gh]

iran-pay (new):
Unified async SDK for six Iranian payment gateways behind one
strongly-typed Gateway trait — ZarinPal, IDPay, NextPay, Pay.ir, Zibal,
Vandar. Each driver targets a specific upstream API version; URLs and
field names are sourced from the providers' published documentation
(verified May 2026 — see VERSIONING.md for the upgrade policy).

Highlights:
* Trait-level API, dyn-safe, runtime-pluggable across providers.
* Toman/Rial Amount type that prevents the unit-mixup bug that ships to production at every Iranian e-commerce merchant.
* Sandbox per provider; .with_api_base() to redirect at wiremock for tests; .with_client() for custom timeouts/proxies.
* MockGateway (no I/O) + scriptable Behavior for unit-testing your own checkout code.
* security:: helpers — constant_time_eq, verify_hmac_sha256 (pure safe-Rust SHA-256 + HMAC implementation, RFC test-vector-checked), check_amount, check_authority_format.
* validators feature re-exports parsitext::validators (national_id, sheba, bank_card with bank lookup, phone with operator detection, landline with province detection, postal_code, car_plate).
* tracing::instrument on every API call.
* Per-feature Cargo gates so binaries can ship only the providers they actually use.
* 53 tests (lib + integration + security), criterion benches, full doc coverage, four runnable examples.
* Per-crate CI workflow with seven feature-combo build matrices plus cargo package.

parsitext 0.1.1:

• NEW: validators::sheba::generate(bank_code, account_type, account) — generates a fully-checksummed Iranian IBAN (matches the iranianbank crate's Iban::new feature; we previously only validated, not generated).
• NEW: tantivy feature with PersianTokenizer + per-token stem filter
  • optional pre-normalization, ZWNJ-aware so compound words like "می‌روم" stay intact in the search index.

jalali-calendar 0.1.1:

• Re-publish at the new workspace version; no functional changes.
• Audited against persian-rs (crates.io); we already strictly exceed its surface (date conversion + 2 validators).

Workspace:

• Workspace package version bumped to 0.1.1.
• iran-pay overrides version to 0.1.0 (initial release).
• iran-pay depends on parsitext = "0.1.1" so its CI cargo-package step needs parsitext 0.1.1 published first.
