chore: bump version 0.10.0 → 0.11.0

dogfood follow-up (PR #149) lands: kebab reset --orphans-only explicit
complement to PR #148's conservative sweep.

minor bump 사유: 새 CLI flag (--orphans-only) + 새 ResetScope variant +
ResetReport additive 필드 = surface 확장. design §10.4 트리거 충족.

 `-j 1` for the full workspace test isn't optional: 18 integration-test binaries each link `lance` + `datafusion` + `arrow` + `tantivy` and the parallel link step exhausts memory (linker gets SIGKILL'd, build silently fails partway). Per-crate runs are fine in parallel.
 
-`target/` is 6–10 GB after a fresh build (DataFusion + Lance + fastembed + 18 × test-binary debug info).

Run `cargo clean` after phase merges if disk pressure shows up; backtraces still resolve to function + line.
+`target/` is 6–10 GB after a fresh build but **balloons to 90+ GB after a few task cycles** (each fb-* batch adds incremental compile artifacts on top of the existing 18 × test-binary debug info). The dev/test profile is already trimmed (`debug = "line-tables-only"`, `split-debuginfo = "unpacked"` — see workspace `Cargo.toml`). Run `cargo clean` **routinely after each merged PR**, not just "if pressure shows up" — disk space is tight and recovery via `cargo clean` is cheap (one re-link per crate on next build). Verified pattern: 92 GB → 0 GB in seconds, backtraces still resolve to function + line.

+//! `kebab-parse-code::javascript` — tree-sitter JavaScript / JSX AST
+//! extractor (P10-1B Task K).
+//!
+//! Implements [`kebab_core::Extractor`] for [`MediaType::Code("javascript")`].
+//! Walks the tree-sitter parse tree (single grammar
+//! [`tree_sitter_javascript::LANGUAGE`] — the JS grammar handles `.jsx`
+//! as well, no second grammar needed) and emits one [`Block::Code`] per
+//! top-level AST semantic unit (free fn, class, each method,
+//! recursively per nested class), each carrying [`SourceSpan::Code`]
+//! with the unit's dotted symbol path prefixed by
+//! [`module_path_for_tsjs`].
+//!
+//! Glue declarations (`import_statement`, bare `export_statement`
+//! re-exports, `lexical_declaration` / `variable_declaration` at the
+//! module level, etc.) collapse into one grouped `<top-level>` (or
+//! `<module>`) unit.
+//!
+//! `export_statement` is unwrapped: an `export function|class` is
+//! treated as the inner declaration arm but the unit's line range
+//! comes from the OUTER `export_statement` so the `export ` prefix is
+//! folded in. `export default function () {}` / `export default class
+//! {}` (no `name` field) emits `default` as the symbol name.
+//!
+//! Differs from `typescript.rs` only by: single-grammar (no
+//! TS/TSX selection) and no `interface_declaration` /
+//! `type_alias_declaration` / `enum_declaration` arms (TS-only). All
+//! other walker behavior (export unwrap with `value`-field quirk for
+//! default-exported anonymous function/class, class-body method walk,
+//! glue flush, post-pass `<module>` → `<top-level>` rewrite) is
+//! identical.
+//!
+//! Scope follows 1A-2 / 1B Task K: AST unit extraction + dotted symbol
+//! paths + line ranges. Per design §3.4 / §9.1 / §9 versioning.

+//! `kebab-parse-code::rust` — tree-sitter Rust AST extractor (P10-1A-2).
+//!
+//! Implements [`kebab_core::Extractor`] for [`MediaType::Code("rust")`].
+//! Walks the tree-sitter parse tree and emits one [`Block::Code`] per
+//! top-level AST semantic unit (free fn, type, trait, macro, each impl
+//! method, recursively per module), each carrying [`SourceSpan::Code`]
+//! with the unit's self-reference symbol path (design §3.4). Glue
+//! declarations (`use` / `const` / `static` / bodyless `mod` / top-level
+//! attributes / macro invocations) collapse into one grouped
+//! `<top-level>` (or `<module>`) unit.
+//!
+//! Doc comments and attributes immediately preceding an item are folded
+//! into that item's line range (design §9.1 "선언 + doc comment").
+//!
+//! Scope is intentionally narrow: AST unit extraction + symbol paths +
+//! line ranges for Rust. The `CanonicalDocument` scaffold mirrors
+//! `kebab-parse-pdf`. Per design §3.4 / §9.1 / §9 versioning.
+//!
+//! Edge cases: a Rust file consisting solely of comments / whitespace
+//! (no fn / type / impl / mod / glue items) yields zero blocks → zero
+//! chunks → not surfaced in search. Safe (no panic) and consistent with
+//! "an empty page produces no chunks" in `pdf-page-v1`.
