Wrap the existing version label in the welcome-banner panel title
('Hermes Agent v… · upstream … · local …') with an OSC-8 terminal
hyperlink pointing at the latest git tag's GitHub release page
(https://github.com/NousResearch/hermes-agent/releases/tag/<tag>).
Clickable in modern terminals (iTerm2, WezTerm, Windows Terminal,
GNOME Terminal, Kitty, etc.); degrades to plain text on terminals
without OSC-8 support. No new line added to the banner.
New get_latest_release_tag() helper runs 'git describe --tags
--abbrev=0' in the Hermes checkout (3s timeout, per-process cache,
silent fallback for non-git/pip installs and forks without tags).
- Strip '_tools' suffix from internal toolset identifiers in the banner
(e.g. 'web_tools' -> 'web', 'homeassistant_tools' -> 'homeassistant')
- Stop appending '_tools' to unavailable toolset names
- Replace 6 hardcoded hex colors (#B8860B, #FFBF00, #FFF8DC) in toolset
rows, overflow line, and MCP server rows with the skin variables
(dim, accent, text) already resolved at the top of the function
Inspired by PR #1871 by @kshitijk4poor.
Adds 4 tests.
