chore: bump deno stack to deno_core 0.412 / deno_ast 0.53

[remi.bezot (remi-bezot)]

Description

Update the Deno runtime stack from deno_core 0.381 / V8 145 / temporal_rs 0.1 to deno_core 0.412 / V8 150 / temporal_rs 0.2.

This removes the Temporal/ICU incompatibility that forces downstream consumers to pin older ICU versions.

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
• Performance improvement
• Code refactoring
• Test coverage improvement

Changes Made

• Updated deno_core to 0.412, deno_ast to 0.53.3, deno_resolver to 0.90, and node_resolver to 0.97.
• Updated the resulting runtime stack to V8 150 and temporal_rs 0.2.
• Adapted the required Deno API changes: #[op2(async)] becomes #[op2], and PollEventLoopOptions::pump_v8_message_loop is no longer present.
• Added the change under UNRELEASED in CHANGELOG.md.

Testing

The full Rust test suite passes with the updated stack, including code mode execution, TypeScript transpilation and type checking, session server execution tests, and doctests.

cargo clippy -- -D warnings was also run. It currently fails on pre-existing lint issues in pctx_codegen and pctx_config; the affected source lines are unchanged by this PR.

Test Coverage

• Unit tests added/updated
• Integration tests added/updated
• Manual testing performed

Additional Context

The dependency update was intentionally kept narrow. PCTX required only a small number of source-level API adaptations for the newer Deno stack.

For downstream consumers, the main benefit is moving off temporal_rs 0.1, removing the transitive ICU compatibility constraint that required older ICU pins.
