[#451] DOCS: audit pre-rc11 CHANGELOG TODOs for Selene 2.x

[aleksandr-kotlyar]

Summary

Audits the old TODO / placeholder sections in CHANGELOG.md that were left before and around the 2.0.0rc10 notes, and turns them into a smaller, evidence-based release-management update.

This PR is intentionally documentation-only:

• no public API changes;
• no speculative cleanup without evidence;
• no broad backports from master.

What changed

• replaced the large pre-rc10 scratchpad TODO blocks with a shorter 2.0.0 release readiness section;
• kept only the items that still need an explicit maintainer decision before final 2.0.0;
• moved clearly non-blocking / future-facing ideas into a Post-2.0 backlog / tracked separately subsection;
• replaced vague TODOs with existing issue references where available;
• removed/trimmed rc11 placeholder items that are already implemented and already documented elsewhere in the changelog;
• corrected the command.long_press(...) note to match the current implementation.

remaining scratchpad ideas (all.* improvements, stacktraces, ActionChains retries, examples, __all__, soft assertions, etc.)	POST_2_0_BACKLOG	No strong evidence that they are release blockers for 2.0.0	Moved out of release-blocking TODOs into backlog summary
outer_html rendering question / Safari text trim	UNKNOWN_NEEDS_MAINTAINER_DECISION	Not enough evidence from 2.x code/history alone to classify as fixed or blocker	Left out of resolved claims; not promoted to release blocker

Why this shape

The goal here is to keep the public changelog readable for users while still preserving release-management signal for maintainers.

The old sections mixed together:

• already shipped work,
• internal design notes,
• future ideas,
• and a few real pre-2.0 decisions.

This PR separates those categories without introducing new product decisions.

Scope / non-goals

Not in scope:

• implementing missing APIs;
• renaming public APIs;
• backporting broader master refactors;
• resolving long-standing design discussions in the changelog itself.

Checks

• git diff --check

Tests were not run because this PR only changes CHANGELOG.md.

Final note

After this cleanup:

• resolved TODOs are no longer left as stale changelog debt;
• the remaining 2.0 blockers are explicitly visible;
• non-blocking ideas are deferred out of the main release notes.
