feat: bump pipeline-tools to v2.1.0

[hoobio]

Summary

Bumps 10 pipeline-tools pins from @v1.6.0 to @v2.1.0 and adopts the v2 Backstage hierarchy routing for Dependency-Track. The Resolve DT channel step now special-cases default-branch so bitwarden-extension@main sits as a top-level sibling of release / prerelease / ci / hotfix instead of nesting under ci.

Channel routing

Event	Channel	SubChannel	MarkLatest	Prune
release event	release	(none)	true	false
release-please prerelease PR	prerelease	(none)	false	true
default-branch push (main)	main	(none)	false	true
feature branch / dispatch / PR	ci	<sanitized-branch>	false	true

Pre-v2.1.0 builds uploaded everything to ci/<branch> (including main), which the v2 hierarchy now flattens via the always-on sweep. default-branch: main is passed so the sweep promotes any existing bitwarden-extension@ci/main to top-level on the first run.

Why

• v2.1.0 cuts the v1 → v2 migration story: legacy ci/<X> umbrellas get re-parented automatically.
• Channel-aware prune defaults (release/prerelease keep all, ci keeps 3, default-branch keeps 10) drop the brittle inline keep toggle. workflow_dispatch still overrides to keep=1 / ci-keep=1 for manual aggressive cleanup.
• Top-level default-branch channel matches gigagrug's pattern, makes the DT UI navigation parity across consumers.

Test plan

• Merge triggers main build → bitwarden-extension@main/<sha> parented under bitwarden-extension@component
• Sweep promotes legacy bitwarden-extension@ci/main (if any) on first run; other ci/<branch> legacies nest under bitwarden-extension@ci
• release-please PR routes to prerelease channel correctly
• Eventual release: published event routes to release with mark-latest=true
