feat(wir): add canonical rule event surface

[Teakowa]

Summary

Implements the canonical Workshop WIR/event surface required by del-rs#8.

• Adds locale-independent WIR representations for filtered ongoing-player events and nine player event identities.
• Extends the canonical catalog with evidence-backed event identities, EventTeam/EventPlayer filters, locale aliases, parameter domains, validation, parser/emitter, dump, and semantic round-trip support.
• Preserves the public parameterless Event::EachPlayer variant as the legacy/default representation of EachPlayerWithFilters { team: All, target: All }.
• Emits legacy Event::EachPlayer as the canonical filtered Workshop event with explicit All / All filters.
• Proves semantic equivalence between legacy EachPlayer and explicit EachPlayerWithFilters(All, All) across supported en-US and zh-CN emission and reparsing.
• Regenerates the pinned zh-CN corpus from workshop-data export commit d854bf01fc7bbf3b2169f67408c07a8da8989ad6: 366/366 exact matches, 0 exclusions.

Closes #12.

Validation

Workshop-rs:

• cargo fmt --all --check
• cargo clippy --workspace --all-targets -- -D warnings
• cargo test --workspace --all-targets
• cargo test -p workshop-rs --test rule_events — 6/6 passed
• cargo run -p workshop-rs --bin workshop-catalog-gen -- check
  • catalog digest: 48b3a07188f7137a8a81e51fc33c06681da5ca5d30b79ee636b0147eb14dfc6d
  • en-US: 366/366; zh-CN: 366/366
• The same fmt, clippy, tests, and catalog gates pass with Rust 1.85.0.

Current Wright consumer verification:

• Companion wright#163 pins workshop-rs to this PR head 3b9a9b6b5ce70921c466268522272abad8aaee34.
• cargo fmt --all --check passed.
• cargo clippy --locked --workspace --all-targets --all-features -- -D warnings passed.
• cargo test --locked --workspace --all-targets --all-features passed.
• cargo build --locked --release -p wright-cli -p wright-lsp -p wright-bench passed.
• python3 scripts/v1-gates.py --wright target/release/wright passed: 6/6.
• python3 scripts/run-scenarios.py --wright target/release/wright passed: 7/7, including the each-player All / All event scenario.
• target/release/wright-bench passed.

No DEL/OSTW-specific types or provider-local event encoding are added. workshop-rs remains the sole canonical Workshop event owner.

Consumer verification is complete against the pushed PR head 3b9a9b6b5ce70921c466268522272abad8aaee34.

• Wright companion PR: wright#163, branch commit 705fa64e9d85a0cd0ae8a31bd120fe126c164c00.
• The companion branch pins workshop-rs to this exact revision; it does not use a local path patch.
• Wright full locked workspace clippy and test gates passed with all features.
• Release build for wright-cli, wright-lsp, and wright-bench passed.
• Release N gate: 6/6 passed.
• Release scenario gate: 7/7 passed, including the each-player event with All / All defaults.
• Release benchmark completed successfully.

The consumer accepts legacy Event::EachPlayer and explicit EachPlayerWithFilters(All, All) as equivalent at the supported reconstruction surfaces. New filtered/player forms remain explicit unsupported boundaries where the current consumer has no target representation.
