Four web files reference moved Rust source files in mirror-comments. `src/events.rs` → `quacker-core/src/events.rs` and `src/mention.rs` → `quacker-core/src/mention.rs` (quacker-core extraction, PR #312); neither exists at the top level anymore. Update these comment references:

- `web/src/anchors.ts` (~L10): `` `src/events.rs::Selector` `` → `` `quacker-core/src/events.rs::Selector` ``
- `web/src/curations.tsx` (~L63): `` in `src/events.rs` `` → `` in `quacker-core/src/events.rs` ``
- `web/src/grapheme.ts` (~L1): `` `src/events.rs::POST_BODY_GRAPHEME_LIMIT` `` → `` `quacker-core/src/events.rs::POST_BODY_GRAPHEME_LIMIT` ``
- `web/src/mention.ts` (~L2): `` `src/mention.rs::parse_mentions` `` → `` `quacker-core/src/mention.rs::parse_mentions` ``

Replace ONLY the path component (`src/events.rs` → `quacker-core/src/events.rs`, `src/mention.rs` → `quacker-core/src/mention.rs`), keeping the `::symbol` suffixes and ALL other text exactly as-is.

Constraints:
- Edit ONLY those four files. Touch no other file.
- In `grapheme.ts`, do NOT change the "Was 300 (Bluesky …)" historical note or any number — only the file path.
- These are all comment / doc references — change nothing but the moved-file path string; no TS/logic/value changes.

This is a mechanical path update for moved files.
