chore(release): prepare 0.46.0

[elkaix]

Summary

• Bumps version 0.45.0 → 0.46.0 across pyproject.toml, uv.lock, README.md, install docs, and the linux-installer README
• Moves ## Unreleased entries into ## 0.46.0 (2026-06-14) in CHANGELOG.md; resets Unreleased to empty
• Syncs docs/en/release-notes/changelog.md via npm run sync
• Adds ## 0.46.0 (2026-06-14) entry to docs/en/release-notes/breaking-changes.md (no breaking changes)
• Updates README "What's New" section with 0.46.0 highlights

Highlights in 0.46.0

• Faster auto-update detection — startup update check runs every 30 min instead of once a day; transient startup network errors retry next launch
• Persistent update notice under the prompt — yellow ↑ Update available line, switches to restart-to-apply after a background install
• Welcome banner robot stays visible in narrow terminals — stacks above the welcome copy below ~68 columns instead of being dropped

Verification

All local gates passed:

• check_version_tag.py --expected-version 0.46.0 — ✅
• check_pythinker_dependency_versions.py (all 5 packages) — ✅
• tests/test_installation_docs.py + tests/test_homebrew_formula.py — ✅ 17 passed
• git grep 0.45.0 leaves only historical CHANGELOG/breaking-changes blocks — ✅
