fix(tui): surfaced skill commands in slash menu

Prioritized /skill:* entries for the empty slash autocomplete query so user skills appear in the initial popup instead of below all built-ins.

Added autocomplete regression coverage for empty slash query ordering.

Fixes #2875

 - Coalesced byte-adjacent SGR sequences in emitted lines into a single `CSI … m`. The component tree styles each span as `<set>text<reset>`, so adjacent spans emit runs of back-to-back SGR sequences (e.g. a `CSI 39 m` fg-reset immediately followed by the next span's `CSI 38;2;r;g;b m`); merging the run is behavior-preserving because SGR parameters apply left-to-right regardless of framing. On a real transcript this drops ~30-40% of all SGR sequences, cutting the per-frame byte volume and SGR-dispatch count a slow terminal engine (e.g. xterm.js/WebGL under a large viewport) must process. Each emitted sequence is capped at 16 parameter tokens so a long adjacent run is split across several valid CSIs instead of overflowing a terminal's parameter buffer (xterm.js caps at 32 and silently truncates, corrupting colors). A run is never extended past a parameter list that ends in an incomplete semicolon-form extended color (`38/48/58;2` missing a channel or `;5` missing the index), so a following code can't be absorbed as the missing component. Disable with `PI_NO_SGR_COALESCE=1`.

+- Fixed empty `/` autocomplete burying user skill commands below every built-in command, so installed skills appear in the initial slash popup ([#2875](https://github.com/can1357/oh-my-pi/issues/2875)).
