docs: update README for v2.6.3

[Manabu-GT]

Release prep for v2.6.3.

• Bump dependency coordinate examples in README from 2.6.2 to 2.6.3 (10 references).
• Add CHANGELOG entry for v2.6.3:
  • New Features — the network request detail screen's "Copy all" export (feat: add copy-all button to export full network request details #268), which resolves item 2 of [FEATURE] Couple of useful features #256.
  • Build — Gradle 9.6.1 (chore(deps): update gradle to v9.6.1 #267).

Internal-only changes in this range (#265 Modifier.Node drag rewrite, #266 rememberUpdatedState cleanup) are intentionally left out of the changelog — no consumer-visible impact.

Docs only; no build or test run required.
