Unescape plain-text fields before persisting to SQLite

[Copilot]

Backslash escape artifacts (e.g. literal \n from CLI argument passing) were being stored verbatim in the DB instead of as their intended characters, reducing readability and requiring downstream post-processing.

Changes

• unescapeText(s) — new exported function in persistent-store.ts; single-pass regex lookup converts \n, \t, \r, \\ to actual characters; all other sequences (unrecognised escapes, quotes, backticks) pass through unchanged

• saveWorkItem() — applies unescapeText to title, description, deleteReason, and audit.text (inside the audit object, before JSON.stringify); structured fields (tags JSON, full audit envelope) are intentionally untouched

• saveComment() — applies unescapeText to comment.comment

// input arrives as: "Line\\nBreak"
// stored in DB as:  "Line\nBreak"  (real newline)
unescapeText('Line\\nBreak') // → 'Line\nBreak'

// double-backslash is handled correctly in one pass
unescapeText('path\\\\file') // → 'path\file'
unescapeText('\\\\n')        // → '\n'  (backslash + n, not a newline)

Tests

• 11 unit tests for unescapeText covering each sequence, multi-sequence strings, double-decode safety, and preservation of quotes/backticks/unknown escapes
• 5 DB round-trip integration tests: description, title, comment body, audit.text (verifying JSON structure intact), and tags (verifying JSON field is not mutated)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/graphql
  • Triggering command: /usr/bin/gh gh issue create --repo TheWizardsCode/ContextHub --title Sample --body-file - (http block)
  • Triggering command: /usr/bin/gh gh issue create --repo TheWizardsCode/ContextHub --title Sample --body-file - /tmp/wl-wt-subse/home/REDACTED/work/ContextHub/ContextHub/tests/cli/mock-bin/git k/ContextHub/Con-C bash text�� commit epo/.worklog/tmpsync 2 rgo/bin/bash init g/data sh bash (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
