feat(oxlint-config)!: ban JSDoc blocks and cap line-comment runs

[zgeoff]

Description

Adds two comment rules to the shared config and removes the one they subsume. A comment now holds only what neither the code, a type, a test name, nor the subsystem doc can hold.

• zgeoff/no-jsdoc reports every /** … */ block; inline @type/@lends casts stay exempt.
• zgeoff/max-consecutive-line-comments reports a run of own-line // comments over max (default 3); tool directives neither count nor join the prose around them.
• zgeoff/no-single-line-jsdoc is removed: it cannot fire once no-jsdoc is on. A consumer naming it must drop the entry, hence the !.
• Neither rule fixes. Deleting prose is a decision, and a silent --fix would hide the report that teaches.
• The repo's own 64 JSDoc blocks are deleted. Nine facts whose reason lives outside the file (an ESLint quirk, a Bun/Node difference, a parser folding rule) return as // lines at the declaration.

Testing

• bun run typecheck passes
• bun test passes
• New tests added for new functionality
