chore: release v0.3.0

Restructure how displays are exposed in Home Assistant:

Each physical monitor is now its own HA device linked to the media-server
hub via `via_device`. The hub keeps the media_player + script buttons; per-
display devices hold the power switch, brightness slider, and the new
capability entities. This lets users place displays in their own area/room
and keeps related entities grouped together in the UI.

New platforms:
- sensor: DisplayResolutionSensor (diagnostic, from EDID)
- binary_sensor: DisplayPrimaryBinarySensor + DisplayPowerControlBinarySensor
  (both diagnostic; help users see why a power switch is or isn't created)
- select: DisplayInputSourceSelect (HDMI1/DP1/...), DisplayColorPresetSelect
  (color temperature), DisplayPictureModeSelect (VCP 0xDC scene modes)
- number: added DisplayContrastNumber alongside brightness

Other changes:
- display_device helper centralises the per-display DeviceInfo; pulls real
  manufacturer/model from EDID; device name no longer prepends the hub
  title since via_device already shows the hierarchy.
- api_client gains set_display_{contrast,input_source,color_preset,picture_mode}
  and stops forcing `?refresh=true` on every poll so HA can ride the
  server's TTL cache instead of triggering full DDC/CI probes per entity.
- select / number entities now check the server's `success` flag and re-
  sync from the actual monitor state when a write was silently rejected
  (some monitors honor reads but ignore writes for certain DDC/CI codes).

Bumps manifest.json to 0.3.0 - the device topology change is user-visible
and existing brightness/power entities migrate to per-display devices on
first reload (unique_ids are preserved).

+### Migration / Behavior Changes
+- Each physical monitor is now its own Home Assistant device, linked to the media-server hub via `via_device`. Existing brightness and power entities migrate to per-display devices automatically on first reload — `unique_id`s are preserved, but entities will move under new devices in the UI and can be placed in their own area/room ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+- The hub keeps the `media_player` and script buttons; per-display devices hold the power switch, brightness slider, and the new DDC/CI capability entities ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+
+### Features
+- **New diagnostic sensors**: `DisplayResolutionSensor` exposes the active resolution parsed from EDID ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+- **New diagnostic binary sensors**: `DisplayPrimaryBinarySensor` and `DisplayPowerControlBinarySensor` make it visible why a power switch is or isn't created for a given display ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+- **New select entities**:
+  - `DisplayInputSourceSelect` — switch active input (HDMI1, DP1, etc.) via DDC/CI
+  - `DisplayColorPresetSelect` — color temperature presets
+  - `DisplayPictureModeSelect` — VCP 0xDC scene modes ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+- **New number entity**: `DisplayContrastNumber` exposed alongside the existing brightness slider ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+- Per-display devices now show real manufacturer/model pulled from EDID; device names no longer prepend the hub title (the hierarchy is already shown via `via_device`) ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+- Select and number entities verify the server's `success` flag and re-sync from the actual monitor state when a write is silently rejected — some monitors honor DDC/CI reads but ignore writes for certain codes ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
+
+### Performance
+- `api_client` no longer forces `?refresh=true` on every poll, letting the integration ride the media server's TTL cache instead of triggering a full DDC/CI probe per entity update ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
