Review: new Bluetooth audio-connect API for Tizen 10.1 (JIRA TWDAPI-304) — audioConnect/audioDisconnect/isProfileConnected on BluetoothDevice, plus BluetoothAudioProfileType, BluetoothConnectionProfileType, BluetoothAudioSuccessCallback, added consistently across all three device profiles (mobile/TV/wearable — 37 matching occurrences of the new symbols in each bluetooth.html).

• Guide prose (docs/application/web/guides/connectivity/bluetooth.md) matches the API signatures: parameter order, optional callbacks, and the profile-type enum values used in the code sample (A2DP) are valid members of both new enums. New section anchor (#connect-to-a-bluetooth-audio-device) matches its ToC link. Dependencies section updated with the 10.1 floor.
• Hand-editing the generated web/api/** HTML is normally out of scope per the tizen-docs skill, but this repo's history shows it's the established pattern for introducing new, unreleased API on a _prepare branch before any external generator has it (e.g. [Web API] Tizen 10.1 prepare added base #2340, [Web API] PPM module added and extended #2353, [10.1] [RPCPort] Add new module for RPC communication #2354, and this same author's prior 05cd9bed1-style commits) — not treating that as a blocker here.
• No conflict with [WebAPI] Links conversion #2399 (just merged into this branch) despite both touching tv/tizen/bluetooth.html — different regions of the file, verified with a local test merge before either was merged.
• Ran check_docs.py --changed-only (borrowing tools/ from master, since tizen_10.1_prepare doesn't have it yet): 0 errors, 0 warnings.

Merging (admin bypass — GitHub does not allow self-approval on a review-required branch).
