A hotkey opens the pastes you keep, and the number key is a position - #32

Release notes

ADDED: QuickPaste. Alt+V opens your saved snippets at the cursor — a map regex, a vendor
search, the whisper you send twenty times an evening. Click one or press its number and it is on
your clipboard. It does not press Ctrl+V for you: you paste it yourself, in the field you meant, at
your own time.

ADDED: the number keys go by the key's position, so the top row picks a paste whatever your
layout prints on it.

ADDED: nine at a time, because that is how many number keys there are. Keep as many as you like —
the ones beyond nine are simply switched off until you switch something else off. Nothing to read,
nothing refused.

ADDED: a QuickPaste tab in Settings to write them, drag them into the order you want them
offered in, and switch them in and out. Adding and editing happen in a dialog; nothing is kept
until you Save, so a delete you did not mean is undone by closing Settings.

ADDED: the popup opens at your cursor, growing down, up, or from somewhere between the two,
whichever fits.

CHANGED: no panel of ours stays on screen when you alt-tab to another application, and one that
was open takes the keyboard again when you come back to the game.

CHANGED: a config.json that has been edited by hand into something unreadable no longer stops
the tool from starting. It keeps what it could read and defaults the rest.

Review notes

ADDED: clipboard_set_text as a platform seam, never SDL_SetClipboardText.

ADDED: an X11 selection owner on a thread of its own — its own Display, poked through a
self-pipe, serving TARGETS, TIMESTAMP, UTF8_STRING, the two text/plain forms and STRING for the
life of the process.

• A selection is a live window answering SelectionRequest, not a place to put bytes: the owner
  has to still be there when the paste happens.
• STRING is served the same UTF-8 bytes deliberately. It is nominally Latin-1, but everything that
  can read UTF-8 asks for UTF8_STRING first, and refusing STRING leaves the rest with nothing.

ADDED: the Windows write, OpenClipboard/CF_UNICODETEXT, retried while another application holds
the lock.

ADDED: kMaxClipboardWrite, 64KB — one XChangeProperty, no INCR on this side.

ADDED: QuickPaste — the model in ppc_core (src/quickpaste.{hpp,cpp}), the popup
(quickpaste_screen.cpp), the Settings tab (quickpaste_tab), and docs/quickpaste.md.

ADDED: the entries in config.json under pastes, and in PRIVACY.md, since they are text the user
typed.

ADDED: picking by number key, read as SDL_Scancode.

• A keycode test would leave the feature unusable by number outside a US layout: the same physical
  keys print ěščřžýáíé on a Czech one.

ADDED: nine active slots. Storage is unbounded and enabled is what competes for a number;
limit_enabled holds the ceiling on config load as well as in the UI.

ADDED: drag-to-reorder on a grip handle, measured in pixels of travel rather than in rows crossed,
and tracked by us rather than by ImGui's held-item id.

• Asking which row the pointer is over only holds while every row is the same height; these are
  two lines and the second wraps, so a move drops the pointer back over the row it came from and
  the list flickers between the two.
• A row's ImGui id is its index, so the frame a move lands ImGui is holding the handle of whatever
  slid into the vacated place.

ADDED: four Font Awesome glyphs — grip-lines, pen, trash-can, square-plus.

ADDED: quickpaste_test — slot ordering, the ceiling, move_paste, the one-line preview on a
UTF-8 boundary, and a config round trip.

CHANGED: the write blocks until the server reports us as the owner, bounded at 250ms.

• The caller hands the focus back to the game immediately afterwards and Wine re-reads the
  selection around that focus change, so returning early is a first paste of the previous
  clipboard. Measured at 0.1-0.7ms.

CHANGED: kOnlyGlyphs is derived from kGlyphCodepoints rather than hand-written.

• The old range covered U+F00C..U+F0E2 because that was where the first two glyphs happened to sit,
  so all four new ones baked as nothing.

CHANGED: nothing of ours stays on screen when the game is present and a third application is in
front — panels included, not only the idle marker. Panels stay up when the game is gone, or they
would be unreachable.

CHANGED: the keyboard focus is re-claimed when the game comes back to the front and on a click into
a panel, not only when the panel opens.

• Our window is override-redirect, so the window manager will never focus it: a panel that lost the
  focus to an alt-tab was left on screen taking no input.

CHANGED: Config::load reads every field inside one try.

• config.json is hand-editable and nlohmann throws as readily on a field of the wrong type as on
  a truncated file, so an object where a string belongs was an uncaught exception before the first
  window.

CHANGED: VERSION to 0.5, in its own commit.
