feat: add per-session :theme colour command#61
Merged
Conversation
Add a pure theme registry (theme.c/.h) of 7 portable 16-colour accent palettes (cyan default, green, magenta, blue, amber, red, mono) and a per-client theme index. The new :theme command (alias :color) shows the current theme and available names, or switches the session's accent. Theming is a personalization only: it changes what the choosing user sees (self-gutter marker, /me messages, INSERT mode chip, MOTD frame, :users/:inbox titles) and never affects other users or server state, in keeping with TNT's unrestricted, anonymous design. Covered by theme unit tests and an interactive :theme regression case; docs and man page updated in the same change set.

Summary
Adds a per-session colour theme command (
:theme, alias:color) — the first item from the "more chat commands" direction, aligned with TNT's unrestricted, anonymous design (personalization only, never affects other users or server state).theme.c/theme.h: 7 portable 16-colour accent palettes — cyan (default), green, magenta, blue, amber, red, mono.theme_index(defaults to cyan; resolved with clamping).:themeshows current theme + available names;:theme <name>switches the session accent; unknown names are rejected with the available list./memessages, INSERT mode chip, MOTD frame,:users/:inboxtitles.Why themes (global parity)
ssh-chat and similar SSH chat servers let users pick colour themes; this brings parity while staying within the 16-colour space so hierarchy never depends on truecolor (2025 TUI best practice).
