[Feature]: Act on grammar/spelling highlights — correct via hover or context menu

[rosspeili]

One-line summary

Highlighted spelling/grammar issues should offer basic correction on right-click or hover — not decoration only.

Problem / motivation

Text is already highlighted for grammar/spelling, but users cannot act on it. Inert underlines feel broken.

Proposed solution

• On highlight: hover popover and/or right-click menu with suggested replacement(s) when available, plus optional session “Ignore.”
• Applying a suggestion edits the field; notes still respect explicit Save if that field is manual-save.
• If the current highlighter cannot supply suggestions: wire something that can or remove custom highlights and use native spellcheck until corrections exist — don’t leave dead UI.

Implementer notes: Prefer browser/spellcheck or offline dictionary; no required cloud proofreading; theme-aware underlines. Out of scope: full grammar AI; project-wide “fix all.”

Alternatives considered

• Native spellcheck=true only (simpler MVP).
• Disable custom highlighting until corrections exist.

Constraints you accept

• Must stay local-first (no required cloud account)
• Should not break existing tracker *.md readability

Mock / sketch / reference (optional)

Squiggle → right-click → “Replace with …” list, same spirit as IDE/browser spellcheck menus.
