fix(tui): complete absolute paths as paths

[helix4u]

What does this PR do?

Fixes a TUI completion routing bug where text beginning with an absolute path, such as /home/d/Desktop/file.md, could enter the slash-command completion path because completion checked only input.startsWith("/").

The submit path already has a stricter slash-command shape check, so this makes completion use the same distinction: real slash commands still use complete.slash, while absolute paths use complete.path.

Related Issue

No GitHub issue found. This came from a Discord support report where an absolute path typed at the start of the TUI prompt appeared to be eaten unless the user prefixed it with a space.

• prompt starting with / eaten
• absolute path slash command eaten
• looksLikeSlashCommand useCompletion
• complete.slash absolute path

Type of Change

• 🐛 Bug fix (non-breaking change that fixes an issue)
• ✨ New feature (non-breaking change that adds functionality)
• 🔒 Security fix
• 📝 Documentation update
• ✅ Tests (adding or improving test coverage)
• ♻️ Refactor (no behavior change)
• 🎯 New skill (bundled or hub)

Changes Made

• Updated ui-tui/src/hooks/useCompletion.ts so completion uses looksLikeSlashCommand() instead of treating every leading / as a slash command.
• Added completionRequestForInput() to keep the completion routing decision testable.
• Added ui-tui/src/__tests__/useCompletion.test.ts covering slash commands, absolute-path-leading prompts, trailing absolute path tokens, and plain text.

How to Test

1. cd ui-tui && npm run type-check
2. cd ui-tui && npm test -- --run src/__tests__/useCompletion.test.ts src/__tests__/useComposerState.test.ts
3. In the TUI, type an absolute path like /home/d/Desktop/agenda/CrimsonRed/.hermes/plans/2026-05-04-HANDOFF-NEXT.md and press Enter. It should be treated as prompt text/path input, not as a slash command.
