- Remove `with_reply_to_id()` method

`reply_to_id` is a field on the activity that is used by the service,
but any changes to it on the bot side are completely ignored. After
thorough testing to confirm, this PR removes the misleading method
`with_reply_to_id`; setting replyToId on outgoing activities is a no-op.

Originally part of #321 but separated out due to timing concerns for GA

## Summary

Brings `main` into `release` for the 2.0.11 release, with quoted-replies
(PR #321) excluded. Also bumps `version.json` from `2.0.0` to `2.0.11`
to align with the teams.ts release cadence.

Single squashed commit.

> **Branch name note**: the branch is `cg/prep-release-2.0.1` (left over
from an earlier draft when alignment hadn't been decided yet). The
actual published version per `version.json` is **2.0.11**.

## What's in this release

- All commits merged to main since 2.0.0 (the previous release),
notably:
  - **Reactions GA** (PR #427) — `@experimental` removed; sample fixed
  - Prompt Preview Support (PR #397)
  - Various dependency bumps and bug fixes

## What's NOT in this release

**Quoted-replies feature (PR #321) is excluded:**
- `prepend_quote()`, `add_quote()` builder methods — absent
- `ctx.quote()` and quote-aware `ctx.reply()` behavior — reverted to
legacy `reply_to_id` + blockquote
- `examples/quoting` — removed
- QR-related tests — removed

**Kept intentionally:**
- `QuotedReplyEntity` and `QuotedReplyData` types stay in the `Entity`
union so inbound activities carrying `quotedReply` entities still parse
- `add_targeted_message_info` runtime strip-QR logic — preserves
prompt-preview cleanup

## Version

`version.json`: `2.0.0` → `2.0.11`

This one-time jump aligns teams.py with teams.ts. Going forward, both
progress on a shared 2.0.x patch cadence.

## Test plan

- [x] `uv run ruff check` — all checks passed
- [x] `uv run pyright` — 0 errors, 0 warnings
- [x] `uv run pytest` — 571/571 tests
- [x] `uv build --all-packages` — wheels produced; consumer install
verified (fresh venv, `pip install --no-index --find-links` succeeds,
`QuotedReplyEntity` importable, `prepend_quote`/`add_quote` absent,
`add_targeted_message_info` present)
- [ ] ADO Public publish pipeline (post-merge)
