Three TS surfaces each carried their own ANSI stripper with different
coverage. The TUI's (OSC, DCS/SOS/PM/APC strings, complete and truncated
CSI, multi-byte non-CSI ESC sequences, stray ESC, C0 controls) is now the
single implementation at apps/shared/src/ansi.ts, exported from the root
index and the new `@hermes/shared/ansi` subpath (ui-tui has no DOM lib, so
it imports the subpath like it does for billing/skin).
Sites (path::symbol → canonical):
ui-tui/src/lib/text.ts::stripAnsi, sanitizeAnsiForRender, hasAnsi
→ moved to apps/shared/src/ansi.ts (text.ts now imports stripAnsi
from '@hermes/shared/ansi' for its own trail helpers)
ui-tui: 13 importers repointed from '../lib/text.js' to
'@hermes/shared/ansi' (createGatewayEventHandler.ts,
components/messageLine.tsx, 11 __tests__ files)
apps/desktop/src/lib/ansi.ts::stripAnsi (2 regexes) → deleted;
parseAnsi/ansiColorClass/hasAnsiCodes stay (styled-segment parser)
apps/desktop/src/app/session/hooks/use-prompt-actions/index.ts
→ imports stripAnsi from '@hermes/shared/ansi'
apps/desktop/src/components/assistant-ui/tool/fallback-model/index.ts
private SGR-only stripAnsi → deleted; imports the shared one
Tests: the TUI 'ANSI sanitizers' cases move from
ui-tui/src/__tests__/text.test.ts to apps/shared/src/ansi.test.ts, plus
one invariant: an OSC-8 hyperlink + DCS string + SGR + partial CSI tail
strips to exactly the visible text with no ESC/BEL left.
Behavior change: desktop chat system messages (use-prompt-actions) and
inline-diff chrome (stripInlineDiffChrome) now also lose OSC hyperlink
payloads, DCS strings, truncated CSI tails and C0 control bytes that the
weaker regexes let through. TUI behavior is unchanged.
