fix: align SDK implementation

[Copilot]

Cross-SDK audit against the Rust core (crates/core/) found binary format, validation, and configuration mismatches.

TypeScript SDK

• EAS chain_id encoding: writeU32 → writeBigUint(BigInt(...)) to match Rust's u64 LEB128 encoding. This is a binary compatibility issue — chain IDs >2³² would produce incorrect wire format.
• URI validation: Regex allowed whitespace (\s) and enforced http(s):// prefix. Rust validates a strict character whitelist only: a-zA-Z0-9.-_/:.
• Sepolia EAS address: 0xC2679f... → 0xC47300... to match Rust/Go.

Python SDK

• URI validation: Regex ^https?://[^\s]+$ accepted ?, #, &, @ etc. Aligned encoder and decoder to Rust's character whitelist.
• Sepolia EAS address: Same fix as TypeScript.
• Test update: test_invalid_url_format now uses a URL with ?/& (chars rejected by the Rust whitelist) instead of "not-a-url" (which only contains allowed chars).

Go SDK

• Default calendar URL: Added missing trailing slash on lgm1.calendar.test.timestamps.now for consistency with Rust.
• Test expectations: TestNewSDK subtests expected 1 calendar / 1 quorum but DefaultCalendars has 5 entries → ceil(5 × 0.66) = 4 quorum. Updated test assertions to match.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
