feat: align with IETF draft-mozleywilliams-dnsop-dnsaid-01 (v0.8.0)

[iracic82]

Summary

• SVCB AliasMode (priority 0) — Discoverer follows alias records to resolve canonical ServiceMode targets per RFC 9460 and IETF draft §4.4.2
• SVCB ipv4hint/ipv6hint — Extract address hints (SvcParamKey 4, 6) to reduce follow-up A/AAAA queries per IETF draft §4.4.2
• DANE dynamic verification — verify() returns context-aware dane_note messages (advisory vs full cert matching) with DNSSEC coupling warning per IETF draft §4.4.1
• BANDAID → DNS-AID rename — All references updated across 35 files (source, tests, docs, metadata). Draft reference updated from bandaid-02 to dnsaid-01. TXT prefix changed from bandaid_ to dnsaid_
• bap SvcParamKey fix — Changed from key65003 to key65010 to match IETF draft §4.4.3 example
• Version bump — 0.7.3 → 0.8.0

Breaking Changes

• bap SvcParamKey changed from key65003 to key65010 — existing DNS records using key65003 for bap must be re-published
• TXT record prefix changed from bandaid_ to dnsaid_ — existing demoted TXT records (Route53, Cloudflare) must be re-published

Test plan

• uv run pytest tests/ -x -q — 750 passed, 32 skipped, 0 failures
• uv run ruff check src/dns_aid/ — all checks passed
• uv run ruff format --check src/dns_aid/ — 50 files formatted
• uv run mypy src/dns_aid/ — no issues in 50 source files
• Verified zero remaining BANDAID/bandaid references via grep
• Verified zero remaining key65003 references via grep
