## Summary

Removes the `:::tip[.NET]` callout block from the reactions in-depth
guide's C# include. The block instructed readers to suppress
`ExperimentalTeamsReactions` via `#pragma` or `<NoWarn>` — that's no
longer applicable now that the `[Experimental]` attribute is being
removed from teams.net (sibling PR).

## Cross-SDK coordination

Part of the cross-SDK Reactions-GA pass. Sibling PRs:
- microsoft/teams.ts#575 — Mark reactions API as GA
- microsoft/teams.py#427 — Mark reactions API as GA
- microsoft/teams.net#509 — Mark reactions API as GA (Libraries + core)

## Test plan

- [x] `npm start` regenerates docs cleanly with no content gaps
- [x] C# in-depth guide renders without the opt-in callout (verified in
local dev server)

## 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)

- `packages/apps/src/microsoft_teams/apps/routing/activity_context.py`

- [x] `poe check` (ruff format + lint) — clean
- [x] `poe test` — 609 passed
- [x] `pyright` — 0 errors, 0 warnings
- [ ] Pipeline build + test stages green on `release` after merge
