fix: support skills whose names start with a number - #9243

💭 I'm focusing on SkillInlineText.tsx, the only file in scope, checking whether its regex matches the shared composerInlineTokens logic that now excludes purely numeric tokens like $1. I want to verify whether SkillInlineText separately filters matches against known skill names to avoid the same false-positive issue.

1. browse_code — apps/web/src/components/chat/SkillInlineText.tsx

2. browse_code — packages/shared/src/composerInlineTokens.ts

💭 Since the regex is gated by the known skill list, something like "$100" won't render as a chip unless a skill literally named "100" exists, so there's no false-positive risk. The only in-scope change is that regex in SkillInlineText.tsx, so I want to check whether it stays consistent with the similar regex used in composerInlineTokens. Given all that, I'm confident this is clean, but since the response needs to follow the required JSON schema, I'll set the state to success and put a clear summary reflecting that everything checks out.
